Hi, I am 27 weeks preg and have had 3 episodes of dizziness, shakiness and the feeling of being encompassed in a fish bowl! went to doc and he said it was because my blood pressure had dropped! He suggested the next time it happens to "put my head between my legs" (entirely possible at this stage of pregnancy...sigh!!). cant seem to find much info online, everyone only seems to be worried about high blood pressure... anyone else have this happen to them??
