Peak OPK then negative

Stephanie
Okay I am currently 4dpo (I think) so figured I would ask this since now I am in my TWW and it will keep me busy.
Has anyone ever... tested in the morning on easy@home test, test wasn't yet positive but definitely there with FMU at 6am. After getting home from working all day around 6pm I tested with an easy @ home and a clear blue. BOTH were peak! Solid smiley and dark lines on the other.  Ofc baby danced. Tested again in the morning just to check to see if I still had the smiley. Still had smiley at 6am, when I got home, tested for fun, was negative and a faint line on the EAH. Did I ovulate while I was at work? Seems weird to me I would assume I ovulated sometime between the first positive and negative. But what's weird to me is I thought usually you get the peak then ovulate 12-36 hours later... idk just wanted to hear if anything else had something similar happen? Curious is all, plus helps me with my TWW talking about something else other than thinking about wanting to test lmao.
