Confusing cycle


Hello ladies. This is my 5th cycle TTC baby #1. This cycle has been confusing and I’m just curious if anyone has any insight. My cycles are typically 28-30 days with ovulation around cycle day 16. This month I never got a positive ovulation test however I did get a very close negative on cycle day 15. According to my temperatures I ovulated around day 14/15. Today and yesterday I have had light spotting (not even enough to fill a tampon throughout the day). I thought maybe my period was coming early but this is super light, my period isn’t due for another week and my temperature is staying high. Does anyone have any insight ??
