Let’s over analyze this 😬🧐 just hypotheticals

So I didn’t track BBT this cycle so this is all guessing. Everything was textbook last cycle but that ended in a chemical. Now this cycle I’m late and going on 19dpo from that first weak peak. Now look on Feb. 7/8 I had a drop of spotting once and that was it. That was around 12dpo so I’m thinking maybe implantation spotting. I did an LH test and HCG. I hadn’t tested LH since the few days after my first peak. The LH was so high but HCG was negative. I’ve been HCG testing every 2 days since then. All negatives on cheapies and FRER as of 18dpo.

So now that I’m late, could it be maybe I had a stronger peak later and caught the down slope of it based on symptoms. And of course I logged BD right around the time I could have possibly ovulated. Like the exact day. So I’m waiting for AF and testing every few days. Maybe I could have conceived on that second peak? What are the odds of this actually happening? I know you ovulate after the first peak but could it have not happened and my body tried again?
