Bled through underwear...miscarriage?

Hi I am (was?) 5 weeks 2 days pregnant, I have had light intermittent cramping for the last week. I just felt something weird so ran to the bathroom and had bled through my panties. It was enough that I put my diva cup in so I wouldn't ruin any more underwear. Is this likely my body aborting? Can you bleed and still be pregnant? How much spotting is normal? :(
