DID I HAVE A MISCARRIAGE!?!?!?

I'm just over 5 weeks pregnant and yesterday I fealt as though I was coming on my period. It got to about half 4 and I went to the toilet to see that i had bled, straight away I panicked and rang for advise. Their was enough blood to cover my underwear but it was pink in colour. For the next 2 hours I had little bleeds if not none (only when I wiped) but it was red in colour sometimes pink. I went to the hospital and they said their isn't much they can do and I have to wait till Wednesday for a scan. Was this a miscarriage or something else?
