If a woman experiences a sagging sensation in her lower body after childbirth, it is often important to consider that the abnormality may be due to a bulging vagina or a mild prolapse of the uterus. For the majority of women after childbirth, the sagging sensation may be present for about a month after delivery and will gradually resolve with bed rest and anal retraction exercises and other pelvic floor muscle repair exercises. Many women with anterior and posterior vaginal wall bulge and mild uterine prolapse can slowly return to normal. If a woman feels sagging in her lower body in late pregnancy, consider that it may be a physiological manifestation of the fetus entering the pelvis. For pregnant women who are experiencing regular contractions, it should be considered as a formal attack of labor, so you should bring all the items you need for delivery and go to the hospital immediately.
