I've been on Loestrin 24 Fe for almost a year, the first month my period lasted for almost month, and then for a couple of months it did what it said, and I only had my period for a couple of days a month, and then in October I never got my period and during Thanksgiving I got it and it was super heavy and lasted over a week, and in December I got it for one day, and I haven't had a period since. I also get tenderness in my breasts, but it goes away, but a few days later comes back. I haven't gained any significant weight, but I also noticed that I keep getting urinary tract infections, which I NEVER had before until I started taking this pill. Its really awful, I hate freaking out over my missed periods, I really wish doctors would inform patients before prescribing this birth control. I feel like I've been used as a guinea pig.
