Are the prenatal vitamins to blame

I'm 12dpo and OF COURSE I'm having all kind of symptoms.

This would be my second pregnancy and it's my first month of TTC.

Anyone else thinks that the prenatal vitamins are guilty of you feeling all kind of things?

Cramps, weird discharge etc..

I hope I'm pregnant of course but can't help feeling the vitamins are messing up with my body (and me!).
