Had sex 2 weeks postpartum had stopped bleeding now im bleeding lot. Heavy and dark. But im cramping too. Is it my period? I can't tell

Too early for sex. And too early for your period, you should have already asked this to the doctor who did your delivery!, since your post partum care is included , you probably are bleeding from your uterus as it is has not involuted all the way from the delivery, or it could be from your cervix, or other causes, you need call the oco who delivered you tonight to see what they want you to do and no more sex.
