Length of LH surge - help required

[Youngoldmum]

Hi
I got fixed smiley on Sunday on my clear blue tests...combined with OV pain & EWCM. Fixed smiley disappears after 2 days so I tested again this morning (Tues) and got fixed smiley again....cheap OPKs also show still surging. No CM at all.
Confused and also worried that a long LH surge might not be a good sign...
Anyone know anything about this?

I also have this. Positive on cb Saturday and then positives on cheap ones until today. I don't know what it means but I'll watch eagerly for any advice!
