Hi Deaks my aim was to have a 2 day cut off and based on previous cycles I seemed to O around 2 days after +ve O test but the month I conceived I think I O'ed 24 hrs after positive O test giving me a one day cut off, one and half days max!! WE also attempted around O+16 - O+20 time, my boys had been conceived around O time with every other day or less baby dancing and DS3 was a 6 day cut off.
Hope this helps always happy to answer any questions
