I am on Implanon birth control. I have it until August 2013. I had my last period (which aren't completely regular) in the middle of January 2013. However, for a few weeks now I have been experiencing many pregnancy symptoms including sore nipples, back pain, food/odor aversions, headaches and nausea. I took an at home test and it was negative but the symptoms won't go away. I want to know if I should go to the local Planned Parenthood and get more answers or if my birth control could be running out. I am a plus size young woman and I know that Implanon may run out earlier in plus size women.

You are aware that no form of birth control is 100% effective?

And those are all symptoms of a thousand other things... that even men and children can get?

Sore nipples are a monthly thing for most women. The rest are not gender specific.
