Clearblue Digital OPK..?!

Mari
Good morning ladies! My AF just ended a couple days ago and so I thought I'd start testing this morning, day 8...and got my high peak face on the Clearblue test?! I've never ovulated this early, is this even possible? I know I'm not supposed to, but I looked at the lines and there were none so I took one of my cheap wondfro strips and there was just 1 line and a very very faint line. Could the Clearblue be messed up? Now it's going to be stuck on peak for two days of so 😕 So frustrated.
