I've been using clearblue OPKs this month. My first test was negative, but since then I've had 6 flashing smiley faces! So frustraiting, I just want a solid smile!
I had the same result this morning (my 6th) so I also tried a forelife test which gave me a very clear positive as the test line was MUCH darker than the cover line.
So I wonder if clearblue got it wrong?
Anyone else used these brands?
