The first menstrual period after an abortion is mostly the same as the previous one, with the same amount and the same color, and basically there are no other changes. However, there are individual differences. Some people may experience insomnia and other phenomena after having an abortion due to anxiety that the body will not be able to recover as soon as possible, which may affect the endocrine system, so the first period may be more or less than before, which is a normal phenomenon. After abortion, you must pay attention to rest, strengthen nutrition in diet, and avoid anxiety so as not to affect the endocrine. However, if the amount of menstruation is significantly less than before, it is recommended to go to the hospital for examination to rule out the endocrine cause of menstrual decrease, but also to rule out the decrease of menstruation caused by uterine cavity adhesion.
