I'm 17 years old and I started taking Loestrin 24 Fe a little over a month and a half ago (I am on my second pack). Since then, i have gotten my period three times, twice in the middle of the pack. They are just like normal periods only with less cramping and maybe a little lighter. But i feel like I am always on my period. This is the only side effect I have experienced, so I am hoping it will just regulate itself.
