OPK & BBT don’t match up?

Hi everyone,
I got my positive OPK on 13th this month. I was on holiday & didn’t wear my sensor to track bbt on the night flight home so I missed CD14 temp. My app has put my predicted fertile window later this cycle as I ovulated CD17 last month. I had physical symptoms of ovulation as well but now my bbt has dipped so no confirmation of ovulation? I’m worried I haven’t ovulated now? Can someone offer some insight!? Thankyou x

@omgz thanks so much for your reply! I was in the Caribbean so it was a 4 hour time difference, and I’ve not been sleeping well since I got home I’m waking up at different times everyday. I’ve signed up to FF this morning and added all my temps in and that’s actually confirmed my ovulation

It's too soon to tell. Wait a few more days and see what happens to your temps. Coming back from holiday/any time difference might mess your BBT around a bit, and your temps taken on holiday might be different to usual too. Or you might not have ovulated yet (could you do some more OPKs to check?).

If you're TTC, it's worth carrying on trying until your sure you ovulated.

Mine didn’t match either but I ovulated. Judging from opk and cervix position and mucus I ovulated Wednesday on cd14 but bbt doesn’t show that. If I only went by cervix and mucus I would have thought ovulation was Monday on cd12. The app has marked it on cd18 which I know is wrong because temps were already too high for ovulation and I didn’t have ewcm.
