"i took quasense for about 3 years and the first two years i loved it. i have tried at least 4 birth controls (oral contraceptive form) and this one was the first to finally work for me. however, within the past year i have had some awful things happening to me and my obgyn thinks it is due to the estrogen in the pill. i had a weight gain of 7 pounds within a week &amp; a half. during this time i was exercising &amp; barely eating to try and get back down to my normal weight. however i only continued to gain weight. i have had so much hair loss this year &amp; now have 4 distinct bald spots. crazy mood swings, i&#039;ve had my period for 2 months straight now, &amp; i&#039;m extremely tired. today i had the iud &quot;skyla&quot; inserted so i hope everything improves soon :("
