There are several follicles in the ovaries, each containing an egg. Ovulation is the process in which hormone changes trigger the ovary to release an egg from a dominant follicle. This egg survives for 12-24 hours during which it can be fertilized. Note that it is not necessary to ovulate in every cycle.
Ovulation patterns can change for each individual and even from cycle to cycle. It typically occurs 12 to 14 days before the start of the next period.
Tracking your hormones during your cycle essentially allows you to understand your body better. This includes seeing the start of your 6-day fertile window with an estrogen rise, observing one or multiple LH surges before ovulation, confirming if you are truly ovulating by detecting a rise in PdG (the urine metabolite of progesterone), and tracking follicle growth with FSH. Furthermore, you can take your daily hormone readings to a healthcare provider if you don't ovulate regularly.
That's a myth. Ovulation depends on many factors, such as your cycle length, hormone levels, etc. It can't be generalized. Ovulation patterns can vary for each individual and even for each cycle. It typically occurs 12 to 14 days before the next period starts.
Generally, only one ovulation happens per cycle. While LH can rise multiple times in a cycle, only one can be the true surge that leads to ovulation. However, in rare cases, a person may release two (or more) eggs at the same time. When this happens, there is the potential to conceive fraternal (non-identical) twins if both eggs are fertilized.
A cycle between 21-45 days is considered normal. It is also normal for cycles to vary in length for the same person. 69% of cycles vary by over 6 days.
This is how your hormones behave throughout your menstrual cycle:
FSH (Follicle Stimulating Hormone): FSH is essential at the start of your cycle; it stimulates the ovaries to develop follicles, each containing an egg, setting the stage for potential ovulation.
Estrogen: This hormone rises significantly 3-4 days before ovulation, indicating the transition to what Inito marks as High Fertility. The increase in estrogen thickens the uterine lining, preparing it for a potential pregnancy.
LH (Luteinizing Hormone): The rise in LH is detected by Inito as Peak Fertility. This triggers ovulation, which usually occurs 24-36 hours after the rise. This is when the egg is released from the ovary, ready for fertilization.
PdG (urine metabolite of progesterone): After ovulation, the ruptured follicle forms the corpus luteum. This produces progesterone and causes PdG levels to rise, helping to confirm that ovulation has taken place. Elevated progesterone supports the uterine lining, maintaining it for a possible implantation of a fertilized egg.
LH, or Luteinizing Hormone, plays a critical role in the reproductive process by triggering ovulation—the release of an egg from the ovary. It rises 24-36 hours before ovulation. Your LH surge may be of different types and all are considered to be normal. Learn more about the types of LH surges here.
Estrogen helps in the growth and maturation of eggs in the ovaries, stimulates the development of the uterine lining to prepare for a potential pregnancy, and triggers the hormonal changes needed for ovulation. Estrogen levels naturally rise and fall throughout the cycle, with a significant peak 4 days before ovulation to mark the starts of the 6 day fertile window. After ovulation, estrogen levels fluctuate as the body prepares for pregnancy or resets for the next cycle. Its dynamic behavior is essential for maintaining reproductive health.
Progesterone plays a key role in confirming ovulation and supporting pregnancy. Its levels remain low during the first half of the cycle but begin to rise after ovulation when the corpus luteum, the structure formed from the ruptured follicle, starts producing it. This rise in progesterone confirms that ovulation has occurred, with levels peaking around 6-8 days post-ovulation. Progesterone helps prepare the uterine lining for a potential pregnancy and supports early pregnancy if fertilization occurs. If pregnancy doesn’t happen, progesterone levels drop, triggering menstruation and the start of a new cycle.
After successful ovulation, the follicle that released the egg is left behind. It is called the corpus luteum. This corpus luteum then releases progesterone. If ovulation has occurred, the progesterone and, in turn, PdG levels in the body will rise after a few days, confirming ovulation. If ovulation has not taken place, there will be no corpus luteum to release progesterone, so ovulation will not be confirmed.
FSH (Follicle Stimulating Hormone) is essential for the early stages of the menstrual cycle, as it stimulates the growth of ovarian follicles. At the start of the cycle, FSH levels rise during the early follicular phase, prompting several follicles to mature in the ovaries. It also plays a crucial role in selecting one dominant follicle that will release an egg during ovulation. Typically, FSH rises before estrogen and LH, but it’s also normal for some individuals to have low FSH levels throughout their cycle without a significant rise.
You have 6 fertile days because the life of your egg is 12-24 hours and the life of sperm inside the female body is 4-5 days. Fertile days include all these 6 days - 4 days before ovulation, the day of ovulation and one day after ovulation. Whereas ovulation is the process of an egg being released from your dominant follicle. Your ovulation day is just one day which is within your 6 fertile days.
Predicting ovulation involves identifying the days leading up to ovulation when you are most fertile, based on hormonal changes or physical signs. This is usually done by tracking the rise in estrogen or LH (Luteinizing Hormone), which occurs shortly before ovulation, signaling the start of the fertile window.
Confirming ovulation, on the other hand, happens after the LH rise has occurred. This is because not ovulating is the #1 cause of infertility. One may get one or multiple LH rises but still not ovulate. Ovulation is confirmed by detecting the rise in PdG (urine metabolite of progesterone) levels, a hormone that only increases after the egg has been released.
Confirmation provides certainty that ovulation has taken place, whereas prediction helps in timing intercourse or insemination to optimize chances of conception.
Progesterone is a hormone which metabolises in your urine as PdG.
First, make sure you've downloaded the free Inito fertility & ovulation app, signed up with your email ID and synced your monitor to your phone as per instructions in the app. Further on, the app will guide you with directions on how to take a test. You can also refer to the user handbook for detailed instructions.
The free Inito app will guide you through all the steps to take a test and use the device.
It is preferable to add at least past 2 periods' dates on the Inito app. If you have the information about more past data, you can choose to add that as well.
The number of tests depends on the irregularity and length of your cycles. For someone with an average cycle length of 30 days, 12-15 tests may be required to predict the fertile window and confirm ovulation. The Inito app will assign tests to you only on the required days based on cycle length and hormone levels.
No, you do not need separate strips. Inito is the only fertility monitor that measures Estrogen, LH, PdG (urine metabolite of progesterone) and FSH on a single test strip. Each test strip is one-time use.
Additional boxes of strips are available in the Shop page in the Inito app. You don't need to purchase the monitor again, that is a one-time purchase.
The steps to take a test are detailed in the Inito app. Here is a summary - Collect your urine in the Inito urine cup, dip the test strip till the bottom of the cup in the urine for 15 seconds, attach the monitor to your phone using the clip adaptor, open the app and insert the strip into the monitor, then wait while the strip processes to give you a result.
You don't have to interpret the results, Inito will give you an explanation of your results on the homepage along with the values. If you wish to understand hormones better, you can refer to this blog. You can also email Inito support at help@inito.com, post on Inito's hormone tracking facebook community, or share the results with a healthcare provider.
Inito gives you actual values of 4 fertility hormones. The interpretation of what the values mean is shown as the following fertility predictions:
Low Fertility: A Low Fertility result appears on days when your chances of conceiving are relatively low. You typically see this result when you are not in your fertile window, which is before and after the days of highest fertility in your cycle.
High Fertility: A rise in estrogen from your baseline levels marks the start of your 6-day fertile window. These days are indicated as High Fertility on Inito, meaning it is a good time to try to conceive.
Peak Fertility: Inito marks Peak Fertility based on a rise in your LH (Luteinizing Hormone) levels from the baseline, which typically indicates that ovulation is likely to occur within the next 24-36 hours. This means it is the best time to try to conceive. Do note, this does not mean that ovulation is confirmed.
Waiting for PdG Rise: After a rise in LH, Inito looks for a rise in PdG (urine metabolite of progesterone) to confirm whether ovulation has taken place. During this period, you are in Low Fertility, and the app indicates it is waiting for your PdG to rise. PdG typically peaks 6-8 days after an LH rise if you have ovulated.
Ovulation Confirmed: When Inito detects a significant and steady rise in PdG (urine metabolite of progesterone) levels after an LH surge, it confirms that ovulation has successfully taken place this cycle.
No, you do not need to take tests every day. The Inito app will assign tests to you only on the required days based on cycle length and hormone levels.
The hormones vary day to day and even on an hourly basis. If low levels of hormones are detected in the morning and the levels increase significantly, the results given may change. It is ideal to use first-morning urine to maintain consistency.
Every new test will need a new strip. The strip can be used only once for the test.
Once you take the test, the app will show the results within a few minutes, along with the fertility prediction based on the result.
Store in the device and strips in a cool and dry place.

Inito measures the actual urinary values of hormones with lab-grade accuracy. It confirms ovulation with 99% efficacy. You can read this research paper to know more.
Ovulation strips only measure one hormone (LH), give yes/no results rather than actual values, and rely on thresholds. In contrast, Inito measures actual values of 4 fertility hormones, and the predictions are based on your own past values rather than thresholds. The values of 4 hormones measured by Inito can help you get your 6-day fertile window and confirm ovulation, both of which ovulation strips cannot do.
You don't have to interpret the results, Inito will give you an explanation of your results on the homepage along with the values. If you wish to understand hormones better, you can refer to this blog. You can also email Inito support at help@inito.com, post on Inito's hormone tracking Facebook community, or share the results with a healthcare provider.
Yes, Inito will work despite these conditions because it measures actual values of your hormones rather than average thresholds.
Inito will show you actual values of your hormones even if your hormones are imbalanced. Further on, you can take these values to your healthcare provider if you are concerned.
Fertility transitions may be a time where your hormones are imbalanced or you may not be ovulating for some time. If you use Inito during this time, it will show actual values of your hormones despite the transition. If you use Inito for multiple cycles, you would be able to see when your body starts to ovulate again.
You can use Inito to track actual values of your hormones over 2-3 cycles to understand your patterns and then opt for at-home IUI accordingly.
After 35, cycles can become irregular, and the chances of not ovulating increase. With your actual hormone values on Inito, you will know about your fertile window despite this. Additionally, you can detect if you're having issues with ovulation early on, so you can opt for medical intervention.
If you don't get an 'Ovulation Confirmed' result for 2-3 consecutive cycles, it's best to consult with your healthcare provider for next steps. They can suggest lifestyle changes or prescribe medications to help you ovulate.
