Question!!

Hi ladies! I have a question. Has anyone on this app gotten pregnant 2/3 days before your last period was due? 
We had sex on Oct 18/19, period came Oct 21st. We did nothing the following fertile week or at all during the month. Fast forward to now and my period is 5 days late. It's never been late. So I'm just wondering if that is even possible?
