Hi guys,
I have used OPK test strips since December. I've never really had a super dark line on them, probably got to the same colour as the other line if not a little lighter.
This is my first month using the clearblue digital, ovulation predicated CD23 (23rd april) I've been using OPKs alongside the clearblue but they don't seem to be matching up.

My clearblue was a circle on CD 19, flashing smiley CD 20 and flashing smiley again CD 21 but my highest level on OPK so far has been CD 19 then went much lower on 20 then a little higher on 21!
Starting to think the OPKs are a bit rubbish? Any advice would be amazing thank you
