I've never had them before, it started when I was about 37 weeks pregnant with my third, Dr said it's pretty common late in pregnancy. Well baby girl is now 2.5 months old, big sister is 2, and big brother is 11. I've had at least 2 a week since they started, I've blacked out twice, mostly I just have shortness of breath, heaviness on my chest, and everything goes fuzzy. Tonight was especially stressful ( 2 yo's food on the floor, baby hysterics, entire kitchen contents on the floor thanks to said 2 yo, she pooped her pants, then my 11 yo caught a roll of paper towels on fire because I left a burner on), I cleaned the poop, put out the fire and collapsed. I couldn't stop shaking, couldn't move or talk, I stayed conscious and could hear everything but I couldn't talk or move. He called my parents and my Mom came over and helped. I still feel weird and now have a headache. This whole 2 under 2 thing is no joke.
