Has anyone experienced passing out while pregnant? I'm 18 weeks today and since Friday I have passed out 4 times. I went to the hospital the first time and they assumed that it was due to low blood sugar but since I had done things to get my blood sugar back up they couldn't say for sure. Also that I was a little dehydrated.. Even though I've been dehydrated the entire time, I have hyperemesis gravedium. I also have placenta previa which has caused multiple bleeding episodes. Im concerned most about the passing out though. All 3 times that it Happened this weekend (after I knew what the problem was) I had been doing all the things I've been told and researched to do to keep my blood sugar up.
