"i got pretty bad mood swings/anxiety with this but worst of all, i got cramps. i had cramps all month long for about 3 months before i switched. it would feel like someone punched me in the uterus and i&#039;d bend over in pain at random times in the day. however, i did experience this with other barr/teva pharmeceutical birth controls. i didn&#039;t get pregnant so i suppose it was effective in that sense."
