"i have been using this birth control for about 3 months. i had no serious side effects. i got bigger breasts and perhaps thicker thighs. i did not gain weight because i still weigh the same. perhaps, i was working out too much (about 3-5 per week) that i gained more muscle on my thighs. there were no mood problems or spotting. i think maintaining healthy diet and working out helps not only to maintain your weight but also be healthy emotionally too."
