i am 18 and i wanted to try the NV due to the fact that i tend to forget the pill some days, i thought this would be perfect. i have started the NV 3 weeks ago and since i have been on it i have been having headaches that will not go away, they are constantly there when i go to sleep and when i wake up again it just wont go away even if i take Tylenol. i have it out now for the week its supposed to be out and the headaches are worse when its out which is really concerning me. also something else i have always used tampons and never once had a problem putting them in or using them and this week i find then very uncomfortable and a little hard to put them it find that it hurts. has anyone had anything similar to this i would like to hear about it and if you suggest that i not continue to use it. Thank You very much! :)
