So this is my first month using clearblue digital, have used OPKs for a few months. Normally I can tell when I'm ovulating as lots of cramping and EWCM. Had my solid smiley appear yesterday morning after 3 days of flashing smiley but I don't think I've ovulated yet. I did an OPK at the same time as I got the solid smiley and it was really low (pic attached). Why would I have a solid smiley? So confused!
