Negative opk's for the past 4-5 days .. haven't tested today ... But had my usual 96.8 temp dip yesterday ... Any similar situations or advice ladies

Last cycle was pushed back really late since I had some unknown spotting for two + weeks .. but when I finally stopped spotting ovulation came around with my low temp and then spike ... With a matching positive opk for the dip ... But this cycle seems weird with no positive opk and this dip .. maybe it's nothing but my temp rose back up .. idk .. any thoughts? 🤷🏽‍♀️
