Who took prenatal vitamins??

Who took prenatal vitamins before conceiving? And how did it effect you? So many people have told me not to take them because of the chances of having multiple babies. Not that it would bother me but Its already risky for me. So I just wanted to know who took them and didn’t have twins, triplets, etc. Me and my fiancé are getting married in a month and are trying for our first baby. We are so excited for the journey and I have only felt like I was born to be a mom for, forever. Any tips would help!!
