ok, so had to go pee as couldn't conatina it anymore!
I had held it fo 3.5hrs and have had half a cup of tea and about 200mls of still fanta.
I used the same brand test as this morning (not a Frer) and I think there is a very faint line? It is late and probably my last pee for the night!
Good news, the brown spotting is hardly there, the dull ache/pressure has stopped and I just have a slight lower back ache. I think that is from the uncomfortable postion I am sitting in whilst at the computer!
will post the pictures in a second...
