I visited a gynaec for my PCOS, as I suffered from severe cramps, due to which I could not attend office. she asked me to take birth control pills, due to which i gained a lot of weight. i was already over-weight, and after this it increased a lot, also the cramps did not disappear rather increased. also even after exercising I am unable to reduce my weight. kindly suggest some medicine whixh would help me reduce weight, without any side effects. I am 5 feet and weigh 70 kgs and have most of fat at the abdomin.
