Prenatal vitamins??

Jenny • Mommy of 4 💕🙌🏻 , 🌈🌈

Is it bad that I haven't been taking prenatal vitamins for most of my pregnancy and I'm already almost thru with this pregnancy?? I'm 29 weeks and 4 days and I take them whenever I feel like it , at first I was having problems taking them because I would throw up right after taking them and this continued till about the last week of my 2nd trimester.
