Free people symptoms and conditions

I went on the NuvaRing because it would regulate my hormones- I have IBS and get sick a few days before my period. The NR was great for keeping my IBS at bay. However, I gained over 15 pounds while on it. I had not changed my eating habits or activity level. The only thing I could associate to the massive weight gain, enlarged, swollen, and sore breasts was the ring. Even after hiring a personal trainer, eating healthier, and working out multiple times a week, I couldn't lose weight. I finally decided to take the ring out. After two weeks of being "ring free", people can see a difference in my weight- and I haven't gone to the gym to work out in over 3 weeks. Now I have to suffer through painful periods and digestive problems because I can't bare the weight gain that comes with the ring. If anyone knows of another form of BC that does not cause weight gain, please let me know.
