Help with spotting! I am terrified!

Salome
Hello everybody. I am 10 weeks pregnant. This is the third time i am spotting brown, red and pink. The first two times when I made the ultrasound everthing was fine. It has been a week since I've been laying at home, stopped working, but the spotting still appeared. It comes when I walk around about ten steps at home. What can I do? This is really terrifying! I do not know what to do! Please, tell me if you've been in a same boat and everything finished fine? Thank you!
