"i don&#039;t think i noticed this at first or even realized the pill was the cause, but this pill gave me terrible headaches for 3-4 days during my period.  i am hungry and moody before my period. the period is very light, which is a plus, but i can&#039;t stand the headaches.  it feels like i have a sinus infection and taking advil non stop doesn&#039;t help.  it&#039;s not worth it.  i would love to have cramps instead of headaches."
