My period cycle is 26 days and I’m 3 dad late. One week later after my period ended I spotted for 4-5 days and it got worse every day. I’ve used the days I spotted as my last period and it now says it’s 3 days late. I haven’t noticed any changes or symptoms at all.. I had unprotected sex after my last period but he pulled out both times. Am I over reacting or is it likely that I’m pregnant?
