Basically about 2 weeks ago I was on antibiotics and me & my boyfriend had sex but I honestly forgot that antibiotics blank out the pill (no hate please I know it was dumb but I had so much on my mind) so anyway for the last few days I've had really bad period pains but I'm not due on till 21st and don't usually get period cramps until a few days before. Also I've been pretty bloated and just feel different if that makes sense. 

What do you guys think could it be implantation or could it just be me please comment me and my boyfriend are going crazy:
