I got on the shot sept 6th. & the doctor told me it would be worn off by dec. 6th. Everything was fine the first month and a half other then being emotional, then the last half I kept spotting after having sex then it led to spotting everyday. And I'm stilll spotting. I still have lower abdominal pains. I still get headaches. And I don't know if I should just go to the doctor or to wait it out to make sure its not just my period trying to level out. I'm also a little worried I could also be pregnant because at the very end of the 3 months like days before I had sex and he didn't pull out in time. So I don't know if all this could be also caused by being pregnant. Any advice?
