Yup, definitely, unfortunately! I only had two weeks off throwing up, and still felt a wee bit nauseous anyway. The reflux wasn't very nice either, and I agree with Kat about BH and vomiting - what a cruel, cruel combination!
However, go for the housework argument! My husband read that abdominal exercises were bad for pregnant women, so banned me from vacuuming. I nearly passed out whilst cleaning the shower once, so was banned from that too. However, I couldn't find a cleaner who actually cleaned
so I had to relax my standards a bit, plus direct the husband.
Fortunately, my husband has always been a better cook than me, so has always done the cooking, as I could barely even reheat food or make some toast for myself without triggering a vomit. The poor man had to barbecue outside some nights so I couldn't smell the meat (although I loved to eat it - go figure!).
Do whatever works for you!
