I only received the shot 3 times in my life and got my period after every three months so am I more likely to get pregnant sooner? So I received my last shot in Dec 2012 and ended in Feb. I got my cycle then but didnt receive my cycle to three months later which was in June, I saw spotting after my period so i thought it was ovulation spotting & I had unprotected sex on my 14th cycle day. So is there a possibility i could be pregnant?
