Big Scare :(

I went to the ER on Thursday early evening because after waking up from a nap, I peed several blood clots and then wouldn't stop bleeding. I was completely terrified, and scared the hell out of my husband. They drew blood, took a urine sample, and sent me for an ultrasound. It was the longest wait time I could ever imagine. The doctor came in and informed me that everything was normal. I was so extremely relieved! The next day I already had an Obgyn appointment scheduled, and although she assured me everything was okay, I'm still so paranoid. Apparently the heavy bleeding is related to two subchorionic hematomas that I have. I still can't decide if that calms me down, or makes me worry more.
