Not ovulating?

I’m hoping someone can shed some light on what I’m experiencing.

- three days of high OPK followed by peak OPK on Tuesday

- have had ewcm for since Saturday

- still experiencing ewcm, 2 days after my peak OPK

- no change in temping (though my temp is always recording as quite low so I’m doubting whether my thermometer is accurate)

I’m wondering whether my body isn’t quite getting over the line to ovulate?

I’ve had blood tests this cycle and hormones are all normal. I had a pelvic ultrasound which indicated I would ovulate on Monday-Tuesday by the size of the follicle.

Has this happened to anyone else?
