Thretened abortion. In this situation?

I am wanting a kind suggestion  that is it possible to recover from threatened abortion and give a normal birth ? since my Dr. said me that I have to wait more three weeks for an another USG and confirm because I am now 7 weeks 5 days pregnant and the first USG on 26.05.2017 showed "a G.S like structure with echogenic rim without any echo". I also noticed some brown blood 3 times on 25.5.17, 3 times on 26.5.17 and till today no sign of blood. From second week of my pregnancy,I had suffered several abdominal pain , back pain. My Dr. also suggested that if heavy blood come or heavy pain notice , attend Hospital on emergency.                   My Doctor  is not very friendly and do not talk with me details. I visited three times to him and each time he gave me only 2-5 minutes.                     I could not understand What I do now in this situation? I now suffered from emotional break down. I need a proper guidance.
