Go to the ER to leave with more questions...

I went to the ER around 7 this morning and I just got back home. I woke up and my spotting had turned into bleeding not really heavy but enough to make me panic because it was coming out almost like I having a period(sorry if tmi). I get there and tell them I'm pregnant. After 30min, I go for an ultrasound to find I had a hidden twin. Baby b was hiding behind baby a same heartbeat or so they thought. Turns out Baby B has no heartbeat. I go to my dr on Monday for a check up but it looks like I'm miscarrying baby B.
