Hello
Been doing a small experiment this month and testing with OPK 4 a day throughout my fertile window here are the results:
CD 16 - Negative
CD 17 - Negative
CD 18 - Positive
7am Faint Positive
10 am Dark Positive
3pm Dark Positive (test line darker than control)
9pm Faint Positive
CD 19 - Negative
I think I have ovulated yesterday evening between 3pm and 9pm what do you think? We DTD on CD 17 and CD 18 - was planning on giving us a rest tonight.
