If you have had a miscarriage for 35 days and still don’t have your period, you may have cervical adhesions, irregular menstruation and the possibility of getting pregnant again. In this case, you need to go to the hospital to have an ultrasound to see the thickness of the uterine lining, and whether there is any fluid in the pelvis and uterine cavity. If there is fluid in the uterine cavity with stomach pain, it may be caused by cervical adhesions, in which case a cervical dilatation is needed to allow menstrual blood to drain out. If the uterine lining is very thick and there is no menstrual flow, it may be caused by irregular menstruation, and you need to take progesterone medication to make your menstrual flow come. If you have sex after the abortion, you need to take a urine test to see if you are pregnant, and if you are pregnant, you need to decide according to your fertility requirements. If you are not pregnant and your uterine lining is very thin, you can take estrogen medication to make your period come back.
