7 weeks and bleeding

Iris
I went to see the dr. On my 7 weeks. heart was great and dr. Said that baby looks healthy. Few hour later I started beeding Rush home and laydown in couch with my feet up have dinner and went to bed. Got up in the morning and not bleeding just some brown recidous when I wipe myself. Dr. Told me that there is nothing that they can do if is a miscarraige but what if is a threatening miscarriage? Can they do something about it to stop it? 
Wish me luck and please share with me if you have had the same experience. 
I forgot  to mention that my morning sickness are gone two days ago.
