Hi I am 21 years old and have been bleeding with clots to the point it has actually threatened my life. I went to the hospital with low oxygen levels and my blood count was at 7 and dropping. I passed tons of clots. Some the size of a mans fist. They said they think its hormones, sent me home w/ because pills, and gave me two blood transfusions. Only thing is the bleeding is still coming and going. When I do have it its still as heavy as it was and when I don't I feel it building up and a lot of pressure. They did an ultrasound and it revealed nothing, miscarriage test was negative, so I don't know what's going on. Can hormones really do this to someone? I also had a stillbirth 5 months ago at 20 weeks. Can that be the cause? I have like every single hyperthyroidism symptom apart from no bleeding. I don't understand. I have been restless, sweating, anxious, my pulse has been 130bpm, and I literally keep hot flashes. Any ideas what could be wrong with me. I am really scared and in need of serious answers.
