Only a few drops of blood on your first period after an abortion is an anomaly. The vast majority of women will resume menstruation in about 1 month after abortion, and the amount of menstruation should be similar to the previous menstruation. If only a few drops of vaginal bleeding occurs, it is abnormal, and we must rule out the decrease of menstruation due to the uterine cavity adhesion. Ultrasound examination is recommended, mainly to know the thickness of the endometrium and whether the echo of the endometrium is uniform. You can take oral medicines to regulate menstruation, such as Bazhen Yi mother capsule, motherwort capsule, and observe the next menstruation. If the next menstrual period is still very small, it is recommended to do hysteroscopy, mainly to separate the adherent tissues in order to normalize menstruation.
