High LH, 3 days from period

Sami

Hey so I took a first response tonight just to see cause sometimes I like to test early, and I see a very faint line but first response is notorious for indents so I decided to take an OPK cause it’s usually super low at this point. But this is the highest OPK I’ve ever gotten and I took two cause I thought maybe it was a bad test. They’re not expired either I double checked. Someone explain!
