The waiting game and prenatal vitamins

Mrs. • Finally have our babies. R.I.P Kimara Jeffers. Welcome 2 handsome boys Allan and Kayden Jeffers. 👧🏾👼🏾👶🏾👶🏾👦🏾
I'm taking prenatal vitamins pills while I'm waiting for two weeks to see if I'm pregnant..... Ugh I hate waiting. Lol. 
Is it a good ideal to take prenatal vitamins pills while waiting to see of your pregnant???
