So long story short I was on the pill for half a year and after I got off in October I still had my period on time even after getting off the pill, every 24th from Nov-Jan. I always use a condom and pull out method when it comes to sex with my fiancé. I started excercising more and I ended up getting a really bad cold after my last period. Is it possible all this could of messed up my cycle? I'm only two days late but I'm freaking out because it's been such a long time since my periods have fluctuated.
