14 wks and in hosp getting blood

I'm 14 wks and currently sitting in hospital for the 2nd night. I was at work yesterday and suddenly had to vomit. I ran to the BR vomited bright red blood. I called my OB, already knowing they were going to tell me to go directly to ER. I arrived and overhear the dr say- so you're pg and vomiting, huh? I look right at him and say- no, its a little more complicated than that! I quickly explained what was going on. He still thought I was a nut but decided to do some labs. They also decided to hang some fluids as well. I also have a blood disorder which makes me chronically anemic. So he comes back about 45 mins later and asks what my hemoglobin normally is. I tell him 10. He says, well, you're down to 8. His mood immediately changes. He says I think its times we call you're OB and call GI and we're probably going to have to transfuse you- have you ever had to be transfused with you're condition? Luckily, no! I'm a nurse and I know they're safe but I'm starting to freak out now! I've seen reactions. So, now my room is flooding with people after people, dr after dr. Then I explain a rash and fever I had a couple of weeks ago so this morning I also had an echo after they also heard a murmur. GI decided not to scope me as its too risky as this point for the baby. They had me on a Nexium drip last night and this morning. Had my transfusion of 2 units of blood last night. I'm now taking oral Nexium. Hopefully I'll be going home tomorrow. Still on liquid diet- ugh! They've drawn blood after blood- when they can find vein- not pretty! Hopefully this will be the end of this ordeal!
