I took Flintstones vitamins during my first and during this pregnancy as well. No matter what I did I couldn't tolerate prenatal vitamins. I take two once a day per my midwife. Just ask your doctor they can help find something that works for you.
I heard you can take Flintstone vitamins instead, but check with your obgyn first. I know my friend had to take those when she was pregnant because pre-natal made her sick.
The gummies are much easier however when I was searching for some at target they did not provide the same amount of vitamins as my current prenatals. Just read the supplement label.
Okay prenatals are a love hate. I hate them but love them for providing my baby with nutrients. This didn't always work but it did most times. Take it at night with a glass of milk. Also have noticed the DHA kind made me really sixk
It probably wouldn't hurt but I'm thinking if you are already puking i would just avoid it for now. Try taking it with a snack right before bed instead. Less likely to puke then.
