"i recently had child number two at age 22 so i dicided to try a new for of birth control was on the pill for two years but got pregnant on it so i got the shot on november 18 and started bleeding on december 1 and it now december 6 and i am still bleeding i am a bit worried seeing that its my first time on the shot i have a little mood swing and lost of energy and lost of appetite. i don&#039;t think i will get another shot if the bleeding doesn&#039;t stop soon and the cramps r painful. i got the shot cause i was told there would be no period and i am still bleeding"
