"i was on loestrin 24 for about 3 years. i switched because i could no longer get the coupon and it was too expensive. initially, i noticed some stomach pain, but i have endometriosis which could have caused that. my periods were non-existent after the first year. i went the entire year without a period. i did not have mood swings until i switched to loestrin 10. over the past few years, i have had consistent weight gain, without changing my diet or exercise routine. i am not sure if that is due to the medication or an underlying problem. i did not notice any breast tenderness/swelling until i switched to loestrin 10 either. i have now switched to generess and am on my 4th day. extreme nausea. i may just pay the $50 for loestrin 24 every month."
