I am now on CD18 and have been getting 'High' since CD14 with no peak.
It's not often I ask for help and advice but I am wondering what's going on this cycle.
One month I continued to test after my 'PEAK' and it soon went back to 'Low' which leads me to believe - I am yet to ovulate.

Symptoms:

Stomach ache for days (as if I am trying to ovulate)
Tender boobs (NEVER have tender boobs)
Occasional Sickness & Heartburn
CD12 - Had a small EWCM / Clear CM (Never usually have ANY)​

Whilst the Clearblue Advanced Fertility Monitor keeps reading 'High' my OPK's remain a very strict NEGATIVE. On CD10 though, I did test and for ''only CD10'' they were almost positive - which makes me believe, maybe I Ovulated before I started using the CBAFM (CD14).

Christmas doesn't exactly feel stressful this year.

It's possible your body was gearing up to ovulate but didn't and now you may ovulate late.

Hmm, I guess so. Could be the 'stress' of this season I suppose. I am more in shock that for 18 months it's been regular O with no delays, then all of a sudden it's either been an early O or will be a late O - or worst case, no O altogether.

I've had strange things happen like that! Like clockwork foreve and then something is off for no apparent reason. Baffles me! Keep on testing though might just be a little late

OPK's not much different today. Going to stop testing and admit defeat now. CD10's line was dark and I didn't test again until like CD14. I'm going to presume for what ever reason I O'd early. We'll soon find out when AF shows, or rather, IF she shows.

If I did O early, there's almost a 99% chance we won't have been successful this month, as we BD'd on CD8 then not again until CD13.

So sorry for the confusion, just wanted to offer some support and virtual HUGS!

AF arrived, two weeks early. For the first time in 18 months, I failed to Ovulate.
