"i&#039;ve only been on this birth control for about a month and i already don&#039;t like it.  i&#039;ve been spotting for about 2 weeks now, i get head aches, vivid nightmares, gained weight, terrible mood swings. the list goes on... the reason why i switched birth controls was because my last one (the depo shot) was giving me extremely bad head aches and cramps. also i bled for 3 whole months while being on it. i just want to find a birth control that fits me and doesn&#039;t give me all of these symptoms."
