FIRST OPK

Breeann

Hi! So glow says I’m supposed to ovulate tomorrow, we BD last night, planning to again tonight, but I just took a clear blue digital opk test and it said my LH was low? I thought I was supposed to ovulate tomorrow? Shouldn’t it be high today? Can I test again later today? Could I have ovulated in the past couple days and still get pregnant from last night? Or is it too late?
