Is it normal to see more than one positive OPK on consecutive days?

Yesterday I felt the urge to POAS early in the morning and got another faint line, marginally darker than previous days. 10-ish saw me get a definite positive - test line darker than control line (although both were slightly patchy but patchy in the same area - IYKWIM). Then yesterday afternoon a slightly lighter test line and then last night, lighter again.

This morning, just to see what would happen I POAS again early and it was as faint as the line at the same time yesterday. THEN at 10-ish came ANOTHER positive. Only difference between todays and yesterdays is that there is nothing "wishy washy" about either line.

What does this mean? My temp dipped only slightly this morning and whilst I still have EWCM it certainly isn't as much as it has been the past couple of days. Maybe Baby is still ferning.

Help please? This is all too confusing!
