Hiya, Kellytarna. To tell you the truth, I don't remember! I didn't even remember that I suffered from headaches until your message popped up. I just remember the nausea throughout my entire pregnancy. Late in the pregnancy, I had terrible nausea and light-headedness from iron supplements (the docs thought it was from the anemia, but I felt fine as long as I didn't take the pills). But the B-6... I just can't remember. Sorry! Maybe there is a different formula you could take?
