Clearblue digital

I've been using these kind of OPK's for a while. I don't ovulate normally. Last month was the first month it looked like I actually ovulated. BFN though. This cycle I started my first round of Clomid on CD 5-9. I started OPK's on CD 10. I had two days of "low". Today on CD 12 I got a "peak". I skipped high and went straight to peak. Is that even possible? I tested with FMU like suggested but I may test again this afternoon to be sure. I have no EWCM either which could be due to the Clomid. I'm just confused because my dr. said I probably wouldn't ovulate until 5-12 days after my last Clomid, which was Friday. Nonetheless we'll be BD'ing!!
