I have only been on it for like 6 days and yet i already feel fat/bloated constipated, emotional, angrey at every little stuipid thing that goes wrong...i ate nothing out of the ordinary today yet i feel like i had huge meals all day long...i felt better when i was off the pill with irregualr periods and just exersisng regularly...it helped better than the pill, my biggest fear is weight gain and i feel like im screwing myself over by taking this i think im going to stop but i keep getting told its just bad the first few weeks and cycles...i dont know if i want to waste 3 months of my life getting used to fake hormons...im done with it! i hate pills
