"i&#039;ve had this for about 4 months now and its stopped my periods completely, i love it as a form of birth control but the main down side is the weight gain. i was 10 and a half stone on the pill before this, now i&#039;m nearly 12 stone in 4 months and have horrible purple stretch marks on my stomach all over. never had stretch marks on my stomach in my whole life. like i said i love this as a form of birth control, especially since its stopped my periods but i can&#039;t deal with this weight gain. i&#039;m exercising more and eating healthier and still the stretch marks come."
