Conception is fastest during the 1-2 days before and after ovulation, and the conception rate is correspondingly higher within 1 week after ovulation, so people preparing for pregnancy can increase the number of intercourse appropriately during ovulation. It is recommended that both partners relax, don’t be overly nervous and anxious, get enough sleep, enhance nutrition, eat fruits and vegetables, quit smoking and alcohol, and exercise properly to conceive in the best condition. You can rest properly after intercourse, and avoid long and strenuous activities immediately, which can cause exogenous infertility. If there are no clear factors that make it difficult to conceive or infertility, it is recommended not to care too much about the time of intercourse, as nervousness is not conducive to conception. If you are not pregnant for a long time after 2 years of marriage without contraception, it is recommended that both spouses go to a hospital specialized in reproduction for examination and, if necessary, in vitro fertilization.
