So yesterday I got a strong positive OPK where my test line was darker. This morning I got another strong positive with FMU where the line was def darker but have just tested now at 3pm & the lines are maybe equal or possibly the test is a bit lighter so would be negative. So do you reckon this means I've ovulated already and my surge is dying down? I'm basically trying to pinpoint my most likely ovulation time. Any ideas appreciated!
