So I have a positive clear blue OPK with a smiley face but on my cheap strip OPKs the test line is still much lighter than the control line. I’ve retested with a cheap strip but can’t retest with my clear blue OPK yet as the smiling face is still showing but will do in a bit. The tests are both in date and used the same sample, followed the individual instructions for each as per the leaflets. Which do I believe? In photo is top is 14 hours ago and the bottom 2 from just now. Other photo is the stick of the clear blue.
