It is possible for a woman with pelvic effusion to affect her pregnancy, depending on the cause of the pelvic effusion. Pelvic effusion is very common for women. It is classified as physiological or pathological. Physiological pelvic fluid does not affect pregnancy. Most of them are caused by follicular fluid flowing into the pelvic cavity during ovulation, and they do not require treatment and will disappear naturally. If the infection is not treated in time, a series of complications will occur, which will easily lead to pelvic adhesions and inflammation of the fallopian tubes, thus affecting pregnancy. In addition, poor hygiene habits can also cause pelvic effusion, such as sexual intercourse during menstruation, untimely cleaning of the vulva, unclean cleaning of underwear, and post-abortion or cleansing surgery infections. If pelvic effusion causes pelvic inflammatory disease, it is important to identify the cause and treat the root cause in a timely manner, otherwise it will have a great impact on pregnancy. Occasionally, if pelvic effusion is found after pregnancy, it should be closely observed to prevent miscarriage due to it. Therefore, women must pay attention to their health, pay attention to the cleanliness of their private hygiene and develop good habits to avoid the occurrence of pelvic inflammatory disease that can affect pregnancy.
