Prenatal vitamins?

Help

I’m due in 7 wks am haven’t taken prenatals in a week idk if this is normal or not but out of nowhere it makes me puke it’s weird but never experienced this before with my previous pregnancy nor this until now. I tried other brand but made me sick as well. One a day was the only brand I wouldn’t vomit after trying a couple last pregnancy. I normally would take them morning or night the same effect happened idk what’s wrong with me! I’m definitely asking my ob next week but i don’t want to take them anymore if I’m gonna be miserable! I didn’t have any morning sickness this pregnancy I felt so lucky but now not so much I tried again today after a week off it and puke within few mins of taking it. Can it affect my baby if I not take them this far into my pregnancy?
