HCG & Progesterone levels

My HCG is 155 as of today's lab draw. My progesterone was 23. Anyone else get a lab taken with those numbers and knew when they ovulated? I'm unsure as to when ovulated. My periods aren't very normal. I could have sworn I had my period on the 1st of August but my husband disagrees with me. The more I think about I'm just not sure anymore when I had my last period. I know that I'm no more than 5 weeks pregnant. I tested on the 15th of August and it was a BFN. Also my digital test said 1-2 weeks preggo and that was on the 28th. Just wanting to get some insight. Thanks to all who respond.
