Birth Control and weight gain.

So I have been on Tri Nessa Lo for probably almost a year year and a half and recently in the last few months I have gained some weight. I used to weigh 116 now I weigh almost 130. I’m seriously thinking about gettin of bc because I wanna feel my normal self again and not have to worry about anything. But then again I know it also has a greater risk of get pregnant. I just wanna feel my normal self again and be back too 116. Any advice?
