Should I stress?

My boyfriend and I had sex 3 days before my period due date according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>. We used a condom but some of the sperm leaked out of the bottom and may have gotten around my vaginal area.Also accordig to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> I am 2 days late this has been stressing me out to the max so I was wondering should I be worried?
