What happened to the unfertilized egg?

I can't seem to find a reasonable answer. Cycle day 50. Positive opk on 10/2... normal period 2 weeks prior. Here we are late as heck but a whole bunch of bfn on hpts. If I know for a fact I ovulated, (glow told me, positive opk and egg white cm) what the heck happened to the unfertilized egg... someone please explain it to me. Dr's appointment on the 14th for annual check up.
