Consecutive positive opk's

Si

I usually get two positive ovulation tests when I check during my ovulation period. This week though, I've had 5 positive tests on different days. Yes it's definitely positive, test line always darker than control and I take it early to late evening. Don't have pcos and have regular periods. Too early to take a pregnancy test, although I did last night and it was a BFN. Two different brands of opk's, same results. I'm not ttc yet, just tracking my cycles.

Has anyone experienced having so many consecutive positive ovulation tests and what was the reason / outcome?
