Okay so I'm 12 weeks i went to my first doctor app at 10 weeks. I been bleeding after having sex with my bf at the end of 8weeks. After dr app i cramped and passed something weird i showed my mother and said it was nothing. I been growing still. Now I'm at my grandparents and bleed through my leggings at my aunts (she a nurse) she said it wasn't enough for a miscarriage. Well now the day before I'm supposed to be heading back home i been bleeding a lot with big and small cramps. No pain though. Do any of you know what could be happening?
