flashing smiley opk

[Lyn13]

Hi all need a bit of help or advice please, this is my 3rd month ttc and have been using clearblue advanced opk, so today is my 5th day testing but the last 4 have been flashing and i now have none left not sure if i will get to the shop today to get more and only have internet cheapie opks. its only ever flashed for 2-3 days in the past cycles not sure why its now 4? would u buy another box now or just keep trying and use internet cheapies? hope this makes sense x

Just use the cheapies if you can't get CB's or you could DTD every/every other day from now so that there's swimmers waiting for the egg.

I know it's way easier said than done but try not to stress too much - your body could simply be taking a little longer to peak the hormones needed to give you a solid smiley this month.

I also use the CB advanced (and have also ran out today :)) and sometimes I go straight to solid smiley, completely missing out the flashy, I've also flashed for 4/5 days before getting a solid.
I'm going to have to use the cheapies again (I don't live in UK and can't get CB's here)

Like anyfuckers said, it can differ per cycle, sometimes you might have flashing ones for longer. If cheap ones work ok for you, you can use them, twice a day or so. If you get new CB ones, you might not get a flashing smiley on the first day of use, but it should pick up the surge.
