Yes try flinestone chewables
i had that with my first pregnancy so i switched to s diff brand n it helped me out ialso would always take them with foor cz the times i took em by themselves they came back up 15minutes later
I use to get sick also but then i started taking them at night b4 bed & that helped...goodluck
I had to take them with a meal and only a small amount of water. If I drank too much water with them I'd puke for sure. I ended up switching to the prenatal gummies and children's chewables (I'd alternate). It is actually best to take vitamins with a meal because you absorb them better.
Always take them with food something in them will make you vomit if taken alone.
Oh and take them atleast ten minutes before laying down to let them absorb that could also have been a factor.
