Ovulation refers to the time during a woman’s menstrual cycle when eggs are released from the ovaries to the fallopian tubes. Having sex close to ovulation is one of the key factors for many women trying to get pregnant. However, for some women, ovulation can be stressful and anxious, which can affect their chances of getting pregnant.

Additionally, women's emotions and stress may affect their body's reactions, such as increased body temperature, increased sexual desire, or increased vaginal secretions. These body reactions can help women predict when they are ovulating, but it can also affect their accuracy.

Therefore, although the impact of tension during ovulation on pregnancy is relatively small, women should relax and enjoy themselves as much as possible during sexual intercourse to avoid excessive tension and anxiety. In addition, women can also help predict when ovulation will be by measuring basal body temperature and observing body reactions, and take appropriate measures to increase the chance of pregnancy.
