If lower abdominal pain occurs after intercourse, it is usually caused by inflammation and is not related to pregnancy. Because the symptoms of pregnancy do not include abdominal cramps, the symptoms of pregnancy may include loss of appetite, nausea, fatigue, morning sickness and other uncomfortable symptoms, which are called early pregnancy reactions. In addition, some women may experience frequent urination, which is caused by the enlargement of the uterus pressing on the bladder. If there is a delay in menstruation after intercourse, along with the above-mentioned uncomfortable symptoms, a urinalysis should be performed to rule out any connection with pregnancy. If you experience lower abdominal pain and increased leucorrhea after intercourse, it is recommended to check the routine leucorrhea and do internal gynecological examination to rule out the presence of adnexal inflammation and vaginal inflammation. If it is due to gynecological inflammation, it is recommended to treat it as soon as possible to avoid affecting the pregnancy in the future.
