What's going on??

Devyn
AF is due on Friday, I've been a little impatient so I've taken a few FRERs, which are all negative. Decided to randomly take an OPK and I can't ignore how dark the test line is compared to the control line. I'm on CD 27, and CM and cervical position both indicate I'm not ovulating and my cycles are pretty regular. Do you ladies know what this might mean??
