So yesterday was my first positive OPK (wondfo, then confirmed w/digital) then today, at 12pm, I took a wondfo and it was positive, then just now, at 3pm, I took a digital to confirm, and it was negative. How do I mark it on the chart? Here are pics below to show you, I took the stick out of the digital to look at the lines. Am I a negative for today or a positive???? To clarify, top pic is Wondfo @ 12pm today, bottom pic is CB Digital negative at 3pm. Thanks!
