UGH…TTW SUCKS!!!!

Not sure if my period is supposed to start yesterday (Jan27th) or the 1st because this is the month after ending birth control. Bled 4th-7th and I think that was just because I stopped my birth control. Just some heavy spotting. Last real period was Dec 21st-26th. I ovulated on the 12th (based on OPKS…my OPKS looked so weird to me but this is my first cycle actively trying) idk what to think. When do y’all think my period should start? When should I test? TTW buddies? opk help? Anything really😭 feeling scrambled.
