Did I have my surge early this morning???

Here’s a pic of my progression. It says I peaked at 5:30 this morning when I woke up. Now at 10:30 it’s negative. Last night it was negative. Is it that quick? Or was that maybe just a random spike in LH.

I have anywhere from 4-6 week cycles (irregular) and this is the first month we are trying with OPK’s... we haven’t got to have sex in 5 days because hubby’s been away..... do I still have a chance??
