Just left the hospital second time in 3 days and they still say everything is ok.. but

Me

So I go to the hospital they tell me everything is fine. Tell me to take Tylenol. Said my pregnancy hormones are still rising so everything is fine. But this bleeding I am having and very severe back and lower abdomen pain suggests differently. I know something isn’t right! Am I wrong? Has anyone else had bleeding like this a went on to have a healthy pregnancy and baby? Or do these doctors have no idea what’s going on. I believe I’m having a miscarriage.
