Chances that got me pregnant ?

I let my husband finish in me, bc I was 2 days late according to Glow, but I “knew” I should be getting my period any day. My period is typically a couple days off based off this app. I was thinking my chances of getting pregnant were super slim - nonexistent since I was about to start. I’m currently 5 days late (not pregnant I have taken 2 tests). & now I’m worried that I might end up with a positive in 2 weeks .... My last period started Nov. 5th and it’s been 3 days since he came in me.
