I've been using my new OPKs, got a faint line Thursday, tested again Friday and line still faint then boobs started hurting as they do each month when I ovulate so I tested today and the line is the same colour as the other one so quite dark. I know I'm either ovulating now or will be in the next 48 hours. Pounced on OH as soon as the line came back! lol
Good luck!
