According to my Dr it stops by about 14 weeks for most, 2% have it till about 18 weeks, and 1% have it throughout the entire pregnancy.
I fall in the 1% :-/
It was very bad in the beginning, like 24/7. I am 21weeks and 3 days now, and it's a lot less thankfully, although still not gone.
Oh try taking your vitamins at night and see if that helps.
Good luck.
Honestly it's safe to say nausea can come and go at anytime during pregnancy, it ended at 20 weeks for me but I'm 34 weeks and it's back my popular demand it's horrible.
And I'm 36+6 now. Not easy
First pregnancy, threw up in the first trimester and done. Now with my second, it was gone by 12 weeks. At around 30 weeks it came back. Is usually in the morning but during the day any smell I don't like is like instant, makes me throw up. Every pregnancy is different
I was 18 weeks. 20 now and still get sick a few times a week. Try Seabands, ******* pops, ginger ale, lemonade and sour candy also helped me. Eat whatever you can and often. I also ended up with Nexium to cut down on reflux and Zofran when I'm miserable
Usually they say 3 monthes but it depends on your body I threw up my whole pregnancy with my 1st.. try ginger ale, cracks, and non greasy foods... fruit helped me also
