Bladder Cancer

Hi everyone, 

I am new here and really don't want to seem insensitive to all of you. But, I haven't officially had a diagnosis.....

So I finally went to the GP as my urine had been a strange colour for around 2/3 months now, I initially blamed this on the vitamins and supplements that I was taking. So, I stopped taking them for three weeks to allow then to fully go out of my system but my urine was still a funny colour. St this point I had started drinking 3ltrs of water each day (Too much, I know)

So I take a water sample whilst waiting to be seen, I see the GP, he dips my pee- clear, clear, clear oh..... erm... (concerned look on his face) you have blood in your urine, he sat back down and said its probably a UTI i will give you 200mg antibiotics for 7 days then you must come back in 3 weeks to be retested, he also put my urine in a bag for me to take to the receptionist to be sent off. 

After looking online I realise my off coloured urine is actually bloody urine and am now very worried. I am very paranoid thinking a lot if the things I feel with my body is indeed an indication of bladder cancer. I feel a pressure in my lower left abdomen quite often but not all the time, from the inside it feels st though there is a little ball in there. 

Sorry if this post isn't okay with not being diagnosed but I am scared. Can I ask what did you feel before you found out? Could you tell that there was something there that shouldn't have been? As it blood in urine? A lot a non visible? 

Thank you x
