I was currently on a period for 3 months, I was placed on norethisterone for 10 days, since I stopped i was bleeding extremely heavy, a large clot like thing came out of me but it wasn't a clot. It was hard not jelly like. Never seen anything like this before. Can someone help. Unsure if its a burst cyst or miscarriage. The pregnancy test came back negative too. Been suffering horrendous pain.
