Mom's pregnancy milk

Hello everyone, I'm 11weeks pregnant , of course I want good health for my baby and good brain develoment for him/her. Please help me, I bought a super known milk brand for pregnant moms, but it seems like I cant take it because everytime I will drink it, just a couple of minutes I vomit, can you please help me what are other alternative milk products for me to support my babys devt? Big thanks!
