I am in the same boat. My morning sickness, in fact all day sickness was pretty bad. Had been vomiting every night after dinner since week 8. Vomiting has gradually became lesser and now at 16 weeks, once or twice a week. For my last pregnancy, I also threw up a lot during the first trimester. But in the end, I had a big baby lol. Don't worry, the baby will still get the nutrients they needed. Just remember to drink more water to keep yourself hydrated. For me, drinking Chinese soup also helps. Jiayou!
