When a woman ovulates, an egg that has matured in the ovaries is released. After this, a journey of approximately 5 days begins before it reaches the uterus. There is now a chance of pregnancy if the egg meets a sperm cell within 24 hours of ovulation. It is therefore a very short period in the woman's cycle when there is a chance of pregnancy. That is why it is important to catch ovulation.

Negative ovulation test
If only one line appears in the control field (C) or if the line in the test field (T) is lighter than the line in the test field, then your ovulation test is negative. You should therefore test again the next day or later the same day if you think ovulation is close.
Positive ovulation test
If your ovulation test shows two lines and the test line (T) is as strong or stronger than the control line (C) then your ovulation test is positive, and you will ovulate within the next 24-48 hours.
Ovulation test will not be positive
If you don't ovulate for a single month, don't worry. It is normal for your body to skip a single ovulation. This can be due, for example, to a hormonal disorder, stress, grief, too much sport, weight loss or, for example, a venereal disease.
In general, a very irregular period can be a sign of a lack of ovulation. If more than 35 days pass between periods, it is very likely that the woman is not ovulating. one of the most frequent explanations for lack of ovulation is PCO.

If you do not ovulate for several months in a row, it is recommended that you contact your doctor.
