No estrogen surge on Clearblue tests - problem?

Hi all, I've been tracking ovulation for a few months with the Clearblue tests that identify 4 or more fertile days. Each month the test goes from blank circle straight to solid smiley face, indicating LH surge but skipping any Estrogen surge.

My periods are normal and BBT indicates I am ovulating.

The leaflet suggests this might mean the LH surge and estrogen surge happen at the same time, rather than one before the other.

I just wondered if anyone has experience of this and been able to conceive - do we need estrogen to surge before LH to encourage EWCM and a generally more sperm-friendly zone - do I have a shorter window to conceive?

Thanks 😊
