weight loss and birth control?

Options
I have been trying to lose weight for years. ive always been the consistent 150-165 but when I went to college i gained the “freshman 15” literally. but while in college i tried my hardest to avoid the freshman 15. it got to the point where i was working out twice a day everyday. for at least and hour and half each time. at the time i was on a strong birth control (the patch) and i think that was the reason on why my weight didn’t change AT ALL nd i was working out for a whole semester which is around 4 months. Now 2 yrs later ive changed to a different BC (the pill) less estrogen and im starting back to workout again ( not as intense) i wanted to know for all the ladies...have you experienced anything like this? if so what did u do? did u lose weight?
