Do contraceptive pills contribute to feeling bloated, moody & weight-gain? also, are they effective for pcos to regulate my hormones & my period?? im on 1x1 yasmin & its been already a week since i started. i feel heavy & bloated. also, moody..

Maybe. Maybe not.: Women with menstrual cycles naturally have gradually changing levels of hormones each day... it's a cycle. The changing levels of hormones affect mood, which means part of one's mood each day is due to changing levels of hormones. Birth control pills have a similar effect... which means a woman's mood on birth control pills may be better, the same, or worse than off pills. It varies among women.
