Currently 11+3 but decided to take a PT during my eighth week. The top test shows a faint line, the bottom test was done using the same urine sample but after it was diluted with water (about 60 urine, 40 water)
I honestly thought the hook effect was a myth! But I suppose it explains why many women who don’t know they’re pregnant get negative tests later on in pregnancy!
Thought I’d share.
