Hi my name is Nicole for the last year every now and then I bleed from my bum heavily but it might only happen every month or maybe even long but I always feel like I havto go to the toilet and wen I try all that comes out is this clear too all the time I have gone to the doctors they have took blood samples and said my blood is perfectly normal for my age (18) I also went to the hospital and they took blood and said it was perfect they referred me to see a specialist and also took my blood and said it was perfect but I would like to know do they check for everything in my blood as it was an emergency in AE web I went to the hospital or do they only check my red and blood white sells would they know from my blood if I had Cancer or HIV or any type of blood disease I am worried
