Bleeding pregnancy after miscarriage

Yessenia • baby #1 on the way! BFP July 27 Due April 2017`
Hey everyone! I had a miscarriage back in April, it was really hard for me but I continued to try & got my BFP last month!im currently 6 weeks,  Everything was going great until last week, I began spotting dark brown very minimal, I didn't think to much of it since I know some spotting is normal during pregnancy. 
Yesterday when I wiped there was actual red blood & in the toilet too. I rushed to my doctor & he said that it may be that I'm at risk of miscarriage but he said sometimes the bleeding goes away and you continue with a normal pregnancy. The blood stopped and now it's back to spotting dark brown. I just hope it goes away. Has anyone experience any sort of bleeding during their pregnancy?
