Actual Ovulation 🤷🏽‍♀️🤔

Sarah-Jane • TTC 16 months💏We did it🤰🏽Sophie born 10/7/18💕
I had a positive on Clearblue and strip OPK test at 3pm Saturday (Cd 14) then positive at 7pm. Positive again Sunday at 1pm (very dark line on the strip test), still positive Sunday evening. Another positive on Monday morning (CD 16) had some cramps sat and Sunday afternoon and my nipples were really sore (stabby pain) last night at around 11pm and itchy?! Still a bit throbbing today. Question is I know after your surge you ovulate 12-36 hours after first positive test but which day would I actually O if my Sunday tests were darker than my Saturday tests (1st positive) ohhh my head 💆🏽😂
