I'm 35 weeks and still have morning sickness. Sometimes it just doesn't go away, but it has lessened over time.
I'm in the same situation, 13 weeks and still have morning sickness, we have to wait and hope we will get better in the other weeks.
If you're throwing up that much regularly, you need to make sure you're getting enough fluids. You are most likely very dehydrated. I'm 26 weeks and I didn't stop having morning sickness until about 20 weeks. I heard sometimes it doesn't really go away
I was sick until 17 weeks and it returned again when i was 30 weeks until i was 32. Its the worst i know. I ended up losing 30 pounds and was hospitalised twice for iv so trust me i know how much it *****. Some poor girls have it the whole way through pregnancy hope youre not one of them. :) all the best.
