Pregnancy

Ok so I miscarried at 6 weeks 5 days found out when I thought I was 9 weeks and then passed everything. They said at hospital that my uterus was empty and just had blood that would flush out. Skip forward to now I am having my first period after all the bleeding. But it's not a normal one very much looks like implantation bleeding. Not heavy no cramping and light. Could there be a chance I'm pregnant and when should I test?
