Prenatal Vitamins

Hey Ladies I’m on a nervous wreck. I haven’t been taking my prenatal vitamins for about two weeks now. I was waiting to be seen by my doctor so she can prescribe me ones that didn’t make me sick. I was seen Saturday and everything is good, she prescribed me some which is now ready to be picked up today due to the holiday weekend but my question is, has anyone not take prenatal vitamins and still went on to having a healthy baby. When I was seen the little one looks like a peanut and I just wanna make sure the growth continues and everything remains ok
