The timing of menstruation in the second month after an abortion follows the normal menstrual cycle. In the second month after an abortion, most women have resumed their normal menstrual cycle. Generally, if the woman’s usual menstrual cycle is 28 days, the interval between the second month’s menstruation and the first month’s menstruation will also be about 28 days. If some women have a menstrual cycle that lasts more than 40 days, they will have to wait more than 40 days for their period in the second month. Some women may have an abnormal period in the first month after an abortion, for example, some may have an early or delayed period, which is often normal, and can be observed for a while, and the period will come normally in the second month.
