I am currently researching birth control methods and the Depo shot seems like the most appealing. Its long term which is what I want I am 18 and dont want kids till my late 20's. I also have terrible terrible menstral cramps, bloating, fatigue ect. The only problem is im really worried about the weight gain I have always had a problem with gaining weight and i don't need more that I cant work off. Im a little worried about taking the pill because im worried I may forge to take it. Any input would be much appreciated. Thanks :)
