Frequent intercourse during ovulation is one of the effective ways to increase the chance of pregnancy, but excessive frequency can increase the risk of infection. Therefore, when planning pregnancy, the frequency of sexual intercourse needs to be carefully managed.

In addition to following the advice above, here are some things to note:

1. Keep clean and hygienic: Before and after sex, both parties need to ensure that their bodies are clean and hygienic. Use clean sex tools and wash your hands promptly after sex.

2. Choose the right time and place: When planning a pregnancy, you need to choose a comfortable and safe time and place to have sex. Avoid having sex if the woman is taking medication or has a chronic medical condition.

3. Control strength: In sexual life, strength and posture need to be controlled to avoid causing harm to women. If a woman feels discomfort or pain, she should stop having sex immediately.

4. Avoid excessive frequency: Excessive frequency can increase the risk of infection. It is recommended to have sex no more than twice a week, and to wait at least 2-3 days before a woman's next menstruation.

When planning a pregnancy, it is very important to manage the frequency of sex appropriately. If you have any concerns or questions, please consult a physician or professional advisor.
