If a follicle is ovulated and you are planning to conceive, the best time to conceive is within 24 hours of ovulation, when the pregnancy rate is highest. In clinical practice, ovulation is monitored and coitus is instructed around the time of ovulation, when the pregnancy rate is higher, especially in the 24 hours after ovulation. If you want to prevent pregnancy, it is not recommended to have intercourse after ovulation. If you have intercourse after ovulation, the chance of pregnancy is very high, and it is recommended to have intercourse 2-3 days after ovulation. If you intend to conceive, it is recommended that you take a urine pregnancy test 2 weeks after intercourse to find out if you have conceived.
