Ovulation Help

Hi ladies, this is my second month TTC and my first time using OPK’s, I think I should have started doing them yesterday but forgot and took my first one this morning. This isn’t my surge yet is it? I feel like it will be tomorrow or Thursday maybe. Just trying to see when I should BD, today then every other day? Or today and continue till I’m on the other side of the “surge” time? Thanks for your help!
