After the abortion, it was delayed for twelve days before coming? I want to ask if this is normal

Patient's question:

After the abortion, it was delayed by twelve days before coming? I want to ask if this is normal? Moreover, the first menstrual period felt redder than before and had a heavier flow

Doctor's answer:

After one or two months, symptoms such as irregular menstruation may appear. Gradually, as hormone levels return to normal, everything will return to normal. Menstrual cramps are caused by uterine contractions. During menstruation, it is best to avoid getting cold and pay attention to keeping warm, which can alleviate menstrual cramps or take Yuanhu pain-relieving tablets.
Advice: It is recommended to rest, maintain personal hygiene, keep warm, and avoid taking contraceptive medications as much as possible, as they can also lead to menstrual irregularities.
