Why can't I get pregnant after calculating the ovulation period?

First, pregnancy requires many factors working together. In addition to calculating ovulation, you also need to be in good health, have no chronic diseases, and have a normal menstrual cycle. In addition, you need to relax, maintain a positive attitude, and believe that you can have a healthy child.

Secondly, calculating ovulation does not guarantee pregnancy. There are many factors that influence a woman's menstrual cycle, including diet, mood, stress and physical health. Therefore, even if a woman has calculated her ovulation period, there is no guarantee that she will become pregnant.

Finally, even if a woman successfully gets pregnant, it does not necessarily guarantee the health of her child. There are many risks during pregnancy, including fetal malformations, maternal hypertension, maternal diabetes, etc. Therefore, even if a woman successfully gets pregnant and gives birth to a healthy child, she still needs to have regular pregnancy check-ups to ensure the health of the child.
