Prenatals?
You might want to switch to another kind or you can try taking at night before you go to bed. Also, there are woman, including myself that don't take a prenatal, we just continue taking our multi-vitamins and other supplements if needed! Have you had your levels checked lately? I had mine done before I had prenatals prescribed and was told my levels were fine and continue the vitamins I was taking (except my iron was high, so they told me to take that every other day verses every day). Good luck!
