This is my 4th pregnancy. 2 miscarriages and my 2 year old son was delivered at 23 weeks. I have never experienced this type of sickness. I'm constantly dizzy and light headed. I've passed out at work multiple times. I've been admitted twice. I was never dehydrated, ate what and when I was supposed to. Baby has been fine thru out it all. 11 weeks today, yesterday's baby's heartbeat was a steady 162 bpm. My heart on the other hand is what's been causing the problems. As far as I know, I was born with a heart defect but that was resolved but now my heart is kind of interfering with my pregnancy. I have to go see a cardiologist in 2 weeks. She's going to put me on a heart monitor for 48 hours and I guess we will go from there. Until then I can not work or drive and I was told to drink twice my recommended water intake. This baby has been giving me a run for my money.
