Sainsburys PT - any good?

[Beaverfeaver2]

I always thought a test was a test, but am now on CD 40 and have had a bit of pink spot come through a few days ago and nothing since.
So I took PT and it was negative.

I have since ready that some are better than others.

I have never had pink spotting before so don't really know if it's something I should look out for either

I used a sainsburys test and i thought it was better than the clearblue ones. I tested 5 days after my missed period with a last minute afternoon wee and got a positive xx
