I was due for my shot in april I went to the doctor and he gave me the patch instead. He said put it on first day of my period. Well I have not gotten my period for 5 years while on the shot. I was not safe with my boyfriend and still no period. My boobs are sore and I feel sick all time. I have taken two pregnancy tests a week apart and both were negative. I have heard some women dont get there period 6 to 12 mths after useing the shot. What do you think?
