So I started using my OPK on Friday. I work overnight so I only took the test on Friday morning,Saturday morning, and this morning. Is it me or is the line getting darker? I had sex today just in case. If I'm not running late for work I'll probably test again when I wake back up. The picture is in order from Friday morning to this morning.
