miscarriage ?

Hey everyone, I think I'm possibly having a miscarriage, and just needed a little advice. I am appx. 6 weeks and 2 days pregnant. 2 days ago I went to the dr for some light spotting and cramping, They did an internal and external ultrasound, we saw the heartbeat, and they said everything looked okay. My blood work came back looking good also. After the ultrasound, I had some bright pink bleeding, which I suspected from the internal ultrasound. It went away, Then yesterday evening I had more bright pink bleeding, then it went away. This morning I had more bright pink bleeding when wiping, and notices my breasts aren't as sore as they were just yesterday. Im worried and upset that the possibility of having a miscarriage is more likely now. The dr won't see me again for 2 weeks, and stated if I have a miscarriage , It would pass easily since I'm not that far along.Can anyone help or explain what a miscarriage feels like. I'm also having very light cramping. Thank you.
