4 days of + OPKs?

[Anonymous]

Has anyone had positive OPKs for several days?

I'm pretty sure I ovulated 2 or 3 days ago (have had 2 high temps the past 2 days and my CM is drying up) but my OPKs have been clearly positive for 4 days (and I'll again at lunchtime to see if it's still + today).

Could an LH surge last that long? And why would the tests still be positive after ovulation?
