I haven't used OPKS yet, if

doesn't show up this weekend, I have a feeling she will, then I'll be using them over Christmas.
I ordered mine from
www.accessdiagnostics.co.uk.
They were £12.75 for 20 and arrived in discreet brown packaging 2 days after ordering.
I've ready a few comments on here from other girls who've tried them and they thought they worked well, so fingers crossed they do for me.
