what day did I O?

okay okay, last time posting during this tww 😬 I'm trying to figure out if I O'd on Monday (per chart) or Wednesday. FF thought it was Wednesday until i told them i had a negative opk on Wednesday. it was quite negative, but i did take it in the evening around 8pm.

i clearly had a shift, but i can't decide which day i think it is.... on past charts, my O date is marked similarly to this one, which makes me agree that its Monday. BUT I had a LOT of ewcm on Wednesday morning and hip pain Thursday.

help? (yes it is a jagged chart & long cycle, i have PCOS)
