I couldn't find where to put this but I need your guys thoughts...Alright so I'm 15 days late now.. Which I'm never this late on my period. Usually it is 1 or 2 days early. But never this late. Me and my bf always have unprotected sex and I know this is a VERY high chance of pregnancy. But me and my bf have been having unprotected sex for over 2 and a half years and we never got pregnant... Now all of a sudden I'm 15 days late! Btw my bf is 19 years old.. My first day of my last period is 03/14/14 and now it's 4/26!! What could be going on? I'll be taking a test soon. Thanks in advance.
