Prenatals

So this is my fourth pregnancy, two resulted in miscarriage, I have a 14 month old boy and I’m currently 11 weeks 3 days pregnant. I had a hard time with prenatals in my first trimester with my son and tried flinstone chewables as well but everything mad me sick(more than I already was). After my 1st trimester I started them back and took them daily until 2 months postpartum. Well I’m in the same boat with this pregnancy and can’t help but feel like I’m hurting my baby because I can’t stomach the vitamins. Any recommendations?
