I am 37 and on my 5th pregnancy. My other children are 13, 10, 8 and 3. Absolutely no morning sickness with the first 3. The 4th pregnancy I was nauseous but able to function. This pregnancy is KICKING MY BUTT! I am so sick 24/7. I lost 5 lbs in 3 days and was getting dizzy while lying down. Went to the doctor yesterday and they diagnosed me with hyperemesis. My BP was 80/50. Additionally, I am so much more tired this pregnancy, I have ZERO energy to do anything (maybe due to dehydration and not eating). But it makes me wonder.....is this an age thing? Or a twin thing? I can NOT handle twins right now so I'm hoping you will all say age.... First ultrasound tomorrow afternoon....currently 7w6d.
