Bleeding after intercourse in early pregnancy may be caused by irritation of the cervix when a woman has cervical erosion, resulting in a small amount of bleeding after intercourse. It could also be the occurrence of a pre-eclampsia and the impact on the uterus during intercourse, resulting in a small amount of endometrial exfoliation, rupture of small blood vessels and bleeding after intercourse. If bleeding after intercourse occurs in early pregnancy, it is important to go to the hospital for gynecological examination and gynecological ultrasound, progesterone and HCG tests. If bleeding is suspected to be caused by cervical erosion, women need to have TCT to rule out malignant cervical lesions and to maintain local cleanliness and hygiene, and intercourse should also be prohibited in early pregnancy. If the bleeding is caused by pre-eclampsia, women need to take proper bed rest and be given fetus preservation medication for treatment.
