Ttc 2nd cycle

Hi everyone. According to glow I ovulated on the 11th. I didn't see the usual cm associated with ovulation until the 13th. However I've done 2 tests and both were negative. One, I left overnight and saw a faint line in the morning but I've been told to ignore this. Anyhoo, af is due today and still no sign of it. Normally I'd have tender boobs and light cramping days before. But no signs. Now I'm wondering of any one experienced this and still got their bfp. Any thoughts?
