I posted a while back about having symptoms, while still on the pill, but my AF appeared and was very normal. However (sorry for TMI) my nipples keep getting darker, but only for around an hour or so, and then they'll return to normal. But I've been looking around for what else it could be, and there doesn't seem to be anything. I'm on Microgynon30, and also Mefenamic Acid tablets for possible endo, but none say that this would be a side effect. I'm just wondering if anyone knows what else it could possibly be?
