pregnancy problems..

Kyla
Okay, so my doctor is worried I'm having twins and we didn't see the second baby at the 19 week ultra sound.. it looks like there are two babies.. I think it would be cool to have twins other than I'm 31 weeks and 4 days and were just now checking. She's also worried I have liver, kidney, and thyroid failure that could cause to me to go into early labor. I'm also gonna be on a heart monitor at home for a month if not the rest of my pregnancy.. does anyone else have this many issues? And have any of you guys found out you were having a hidden twin?
