For anyone entering this world of trying to conceive or for those just getting to know each other, knowing when to start ovulation tests is critical! So I created a fertility table where you can know exactly what day of the cycle to start doing ovulation tests. This fertility table fits in regular or irregular cycles that can still allow the fertile period to be detected even before ovulation arrives . So how about better understanding this one contained?
We know that in a normal cycle or considered to be 28 days in duration, ovulation would occur exactly in the middle of the cycle, on the 14th day. However, as not all women have such perfect cycles, the fertility table helps a lot. For example:
Women with 30-day cycles: The most fertile day would be the 16th day. However, fertility tests should be started on the 13th day of the cycle to follow the evolution of the line guided by the LH hormones.
Women with 21-day cycles: Early ovulation of these short cycles calls for fertility tests to begin on the 6th day of the cycle. So that you can detect ovulation in which the ovulatory peak would be on the 8th day of the cycle.
For irregular cycles, it is up to the woman to average the duration of the last 3 cycles. Let’s say the longest cycle was 43 days and the shortest 30 days. She should consider her fertile period from the 13th day of the cycle to the 25th day of the cycle. The tests should be started from the 13th, 14th or 15th day of the cycle to monitor the evolution of LH in the body. As there are more than 10 days of follow-up with daily fertility tests , this woman must have a slightly larger stock of ovulation teststhan a woman with regular cycles, or do another follow-up such as the basal temperature, which will also help to detect the most fertile days. Although the table is very useful, it is worth remembering that your cycle will not always be a rule, even for women with theoretically regular cycles, the fertile periorum can change! A few days more or less but it is possible. That is why it is recommended to always check your body and start testing as soon as the first sign of ovulation appears.

These tests work perfectly well, since the base you have on the tablet to get pregnant would be the ovulatory LH peaks. This hormone is responsible for ovulation itself, they are detected by fertility and ovulation tests. The darker the line, the closer the woman’s most fertile day is.
The organism, before releasing the egg, causes the LH peak to rise and it is considered positive in the ovulation test when the test line is equal to the control line or possibly darker . The darker, the closer to ovulation is to happen. We can say that in 12 to 48 hours ovulation happens. That is why doing the tests first is so important. The fertility table will indicate the day on which the woman should start the tests in order not to miss the hormonal peak, and as a result pass beat in ovulation.
The best way to do the ovulation test without losing your LH peak is in the afternoon! Contrary to what many women think, the period from 4 pm to 7 pm is the best time to capture fertility hormones, in this case LH . It is not advisable to do it before 12 pm, because at this time, these hormones are at very low levels.
Its peak occurs exactly in the afternoon. We must remember that women who use ovulation inducers are at risk of having this LH peak for longer or not even taking the tests with super dark lines. Remember the fertility chart will work best on regular cycles, but it can work well for irregular cycles. Do not forget to count the average of your last 3 cycles to determine the fertile period and also the days when you must start fertility tests and never forget that the cycle may change from one to another in the same year.
My name is Dr. Alexis Hart I am 38 years old, I am the mother of 3 beautiful children! Different ages, different phases 16 years, 12 years and 7 years. In love with motherhood since always, I found it difficult to make my dreams come true, and also some more after I was already a mother.
Since I imagined myself as a mother, in my thoughts everything seemed to be much easier and simpler than it really was, I expected to get pregnant as soon as I wished, but it wasn’t that simple. The first pregnancy was smooth, but my daughter’s birth was very troubled. Joana was born in 2002 with a weight of 2930kg and 45cm, from a very peaceful cesarean delivery but she had already been born with congenital pneumonia due to a broken bag not treated with antibiotics even before delivery.
