"when i first started this birth control i thought that it actually improved my mood but after a couple months on the pill i have become extremely irritable, i start fights with my boyfriend constantly that end up in screaming matches, and just overall an angry person. that is not how i was at all before taking the pill. the pill has been effective in preventing pregnancy in two ways, one it&#039;s intended way, and two hardly any sex drive save for when i&#039;m actually on my period. i don&#039;t think this is the birth control for me and i will be switching after i&#039;m through with my last box next month."
