"i have been on this pill for almost 3 years. i think its a little silly seeing people who have only been on this pill for a month-under a year comment on here because i did not see the effect this pill took on me until a year or two down the road, but i suppose everyone is different. anyway, for the first 9 months- a year or so i was experiencing minor headaches from this pill, i did not gain or lose any weight that i was aware of, but i am also a very active person. further, my period was nearly constant for the first few months on the pill, &amp; prior to starting microgestin my period was very regular. i could predict its start &amp; end dates easily &amp; it came right on time every month. now however, i rarely have a period at all, &amp; its awesome!"
