I'm 27 weeks pregnant with my 2nd child. 1st pregnancy about 29 weeks I was told I had hyperemesis. I've been fighting to keep food and water down and have put myself on a bland diet in an attempt to hold off the vomiting spells for as long as possible. Today at work I started to feel light headed, felt like my heart was racing, felt sweaty and weak, like I was going to pass out. It had only been 2 hours since I had eaten. Are these spells normal for this time in a pregnancy, or should I be calling the doctor
