pee stick analysis help please!!

Ma
Hi guys not sure if this is he wrong place to put this but I need help! The first two months off of BC I was getting positive on my lil pee tests for day 18 for ovulation. Last. Kath seemed inconclusive with my pee tests and I figured I just "missed" my surge... idk. Then this month my period came a week late.
So since we're waiting til Dec to really try to get pregnant I have been trying to temp this month... now my real issue is I finished my period and my strips were pink the day after my period ended.
Can anyone help me determine which day I must have ovulated? And why is it right after my
Period? So weird! I haven't even gotten any CM or ewcm.
Yesterday 9/17
