I’m 31 weeks and 4 days, and a first time Mom. Last week I got really dizzy in the middle of class (I’m a teacher) and really hot, then threw up a lot. Since then, this has happened twice. I told my midwife after this first time and have had two more “episodes” since then. The nausea and vomiting doesn’t bother me...it’s how quickly this hits me. I will feel fine and then it feels like I completely crash and can barely keep from passing out. My glucose test was normal and I don’t have any sugar problems that I’m aware of. The episodes last only a minute or so but sometimes repeat a couple of times back to back until they pass altogether. Is this just normal 3rd trimester stuff or the sign of something more serious?? Anyone else experience the same thing?
