Glow chances of pregnancy predictor vs clear blur digital.

Loz

Ok this month when I got my positive opk which with clear blue you get a smiley for 2 days. The following day my glow ap said I had a 2% chance of pregnancy. I was confused as I would of thought pregnancy chances would still be high at this stage? I had inputted the positive test in the ap. So whens the best time before ovulation or after to TTC? I'm working on the need partners sperm to regenerate theory of every 3 days.
