It helped me to take mine at night rather than in the mornings.
My first pregnancy they made me sick no matter what. You can switch to Flintstones and iron pills or I've heard they now have a gummy prenatal. Would've been nice to have 3 years ago lol
You can also find some that are all natural food based one organics i ive been drinking them since i found out i was pregnant and they are great i love them..i buy mines at whole foods matket a little price but their really good i can take them on an empty stomach or after i wat and i dnt throw up and best thing about them is everything you drink in the pill is natural and organic.
Try the gummy ones there good
