I have been taking Loestrin24Fe for about a year and 2 months. Everything was going fine, no adverse side effects, just lighter shorter periods, until about the 8th month...when I skipped my period. I freaked out, however, was not pregnant, and continued to have either normal or real light periods after that. Now, about 14 months into taking the pill, I skipped my period again (2 negative pregnancy tests), and have been feeling anxious, and moody to the point where it's scaring me, I don't know why I have been acting the way I have...depressed...moody...anxious. I'm going to the gyn tomorrow -while I'm there I'm gonna ask if i should stay on it or what is going on? I'm afraid to switch to another pill..they all have their horror stories it seems. but I'm afraid to stay on this also. does anyone know why a doctor may say its "normal?" thanks!
