Peak on Monday but no BBT rise today. Should we DTD tonight?

[SneezySue]

I got my peak ovulation test on Monday afternoon so I assumed I would ovulate yesterday (Tuesday) and then have my BBT rise this morning (as measured by my Apple Watch).

However there was no temperature rise today! So I guess my first question is, does anyone else use ovulation tracking on the Apple watch and how accurate is it?

Is there a chance I ovulated today instead of yesterday?

Should we DTD before bed tonight?!

Should DTD every other day during fertile window. These are prediction kits - it's not a definitive timeline.

BBT is a flawed metric - but use it if it works for you. So long as you also do LH tests.

I agree with the pp, when I was ttc for years, the gp said that trackers etc were not completely reliable and the best thing to do was dtd every other day in the fertile window
