If you experience stomach cramps 1 month after your abortion, most of them are a precursor to your period coming soon. After the surgery, the vast majority of patients resume menstruation 1 month after the surgery, and before they get their period, they experience stomach discomfort and breast tenderness. However, there is another condition that may be caused by adhesions in the uterine cavity. Due to the damage of the endometrium after the surgery, if the endometrium is not repaired well, it will lead to the adhesion of the endometrium, which will lead to the adhesion of the uterine cavity. In this case, there is no way for the menstrual blood to be discharged naturally, and all of it is stagnant in the uterus, which can cause the patient to experience significant swelling and pain. So, if it is the case that the menstruation has not come either, an ultrasound may be needed first. For patients with suspected uterine adhesions, a hysteroscopy is needed.
