Normally, you should have your period about a month after a painless abortion. A woman’s menstrual cycle is normally constant (i.e., once in 28 to 30 days) and should follow the normal cycle after an abortion. If menstruation is normally delayed by about 40 days compared to the daily menstrual cycle, the time of menstruation after abortion will also be delayed accordingly. Therefore, if you normally have regular periods, it is normal to have your period about one month after the abortion. If you do not have your period after your usual menstrual cycle, you should consider whether it is due to the endometrium not recovering or to uterine adhesions. There is also a possibility that the endocrine system has not fully recovered after the abortion, which may cause the absence of normal menstruation. In these cases, you need to go to the gynecological clinic of the hospital for relevant examinations, and then carry out symptomatic treatment according to the results. In addition, patients need to supplement their nutrition after painless abortion. A high-protein diet can be given to promote the recovery of the organism, so that the menstruation can come normally.
