Not pregnant during ovulation

First, there may be problems with a woman's body and reproductive tract that may affect a woman's ability to get pregnant. For example, women suffer from reproductive organ diseases, such as fallopian tube blockage, ovarian disorders, etc. These problems may affect the woman's eggs and ovulation, resulting in difficulty in pregnancy. In addition, women suffering from certain immune system diseases, such as AIDS, may also have difficulty conceiving.

Secondly, women’s psychological state may also have an impact on pregnancy. For example, negative emotions such as anxiety, depression, and stress may affect women's reproductive functions and make it difficult for them to become pregnant. In addition, women suffering from certain psychological issues, such as sexual orientation issues, may also affect their ability to become pregnant.

Finally, women's reproductive environment and conditions may also affect their ability to become pregnant. For example, the size, location, and function of a woman's uterus and ovaries can affect their ability to become pregnant. In addition, women's weight, age, health, etc. can also affect their ability to become pregnant.
