The best time to review ultrasound after a woman has had an abortion to terminate a pregnancy is usually about 14 days after the procedure. In the early post-abortion period, the uterus is not fully normalized and there is obvious residual tissue accumulation in the uterine cavity, so it is meaningless to review ultrasound too early. If the ultrasound is repeated 14 days after abortion, it is possible to determine whether there is residual tissue in the uterine cavity and to observe the recovery of uterine contraction at the same time. If the ultrasound is reviewed too late, it may not be able to detect the residual tissue accumulation in the uterine cavity in time, and the adhesions occurring in the tissue residue for a long time may increase the difficulty of the clearance operation and cause more damage to the uterus. In addition, women should rest in bed after abortion to terminate pregnancy, pay attention to warmth, avoid staying up late, regular rest and rest, reduce outdoor activities, timely replenishment of nutrients, eat more fresh vegetables and fruits, less spicy and stimulating food, and prohibit sexual intercourse before the next menstruation to promote the recovery of various body organs and tissues as soon as possible.
