Clear blue and Tesco positive but pink dye negative

[sam.xx]

Hi, just wondering if anyone has had the same problem I have had 2 clear blue digi positive 1-2 weeks also 1 negative. Clear blue fast as easy positive and Tesco positive but the pink dye test don’t seem to show anything at all ? Doctor wouldn’t do bloods as he says a lines a line but just wondering why it doesn’t come up on them.
Thanks S x

For you know the sensitivity levels? And which tests did you do first? Or have you used both each time?x

I'm so sorry to jump in... Can I ask which are the more sensitive to use? Or how you check? Xx

If in the UK One Step ICs you can buy from Amazon are 10mIU, Cassanovum are the same but give false positives, Superdrug Early are 10mIU, Boots early are 15mIU, Clearblue early detection are 10mIU, FRER are apparently 12.5mIU, Clearblue Plus are 25mIU, Clearblue digi with conception indicator are 25mIU, Clearblue early digi are still 25mIU ... there are other tests like Signalab and others on Amazon which are also 10mIU
