If you are planning to get pregnant, it is recommended that you do not cleanse immediately after intercourse because standing immediately after intercourse reduces the chances of getting pregnant by 50% because a large amount of sperm will flow out of the vagina, which reduces the amount of sperm entering the uterine cavity, so the chances of getting pregnant are reduced. It can be cleared the next day. After intercourse, it is recommended that if you have a retroflexed and retroverted uterus, it is recommended that you lie on your stomach in the prone position and rest for an hour so that the cervix can be immersed in the semen to increase the chances of pregnancy; if you have an anteriorly flexed and anteriorly tilted uterus, you can put your buttocks up after intercourse so that the cervix can be immersed in the semen to increase the chances of pregnancy.
