Bleeding on and off

Iam roughly 6 weeks , and around 7.30 pm last night I starting bleeding , bright red blood this lasted an hour . Then at 11am today the same thing happened only this time there was a small dark red clot ( almost period like) I have no cramping . I have not had a bleed since but have a funny feeling down below that there could be more blood to come . Is this a miscarriage ?
