It's hard to say as this is my first 'proper' cycle since coming off the POP and Nexplanon together. My first time temping too, and it was a bit all over the place. If assuming a 28 day cycle then I would be due AF tomorrow, but - if the chart is right - I either didn't Ov or I may have Ov'd at CD 17 as there was a temp dip that morning followed by a rise.
I'll probably wait until Monday if no AF over the weekend...
