Not taking prenatals

Liz β€’ Angel baby 05/05/15 TTC 2+years Married. Currently 26 weeks pregnant with πŸŒˆπŸ‘ΆπŸ½. πŸ™πŸΌβ˜ΊοΈβ˜ΊοΈ
So I'm about 12 weeks pregnant and haven't taken my prenatals in weeks! I do however take folic acid every night. Should I be worried? I stopped taking them because I couldn't keep anything down and felt so sick for the past weeks. MS is easing up a litttttttlllleeeeee bit and plan on taking them now. Any insight on this?
