Late and losing hope. I was wondering...

So my normal cycles are 30-31 days. Today is CD 36. Had weird pains in lower abdomen yesterday. Not super painful but felt like little shocks that lasted a few seconds. First on the left but primarily on my right side. All day. AF was predicted to start on the 14th. So I'm late. Took a test this afternoon just to see at about 1:30 (I know FMU is best. Took the test with at least 2 hours between bathroom visits) and took a pic of it at 1:35ish. In person and on the pic I couldn't see anything. Left it on the bathroom counter. Forgot it was there. Well I go into the bathroom about 6:30 and see a vvvfl. I know it's probably an evap being 5 hours after I took the test. But I wondered if this has happened to anyone before and they still ended up getting a BFP later?

Test at 1:35

Test at 6:30
