Pregnancy after miscarriage

Sophie
On the 4th May 2016 I had a D&C, because we found out at my 12 weeks scan the week before that we had lost our child just after 6 weeks of pregnancy. However, no period has come and I have done multiple tests coming back that I am pregnant, also had a blood test which I'm finding out the results on Monday. In such a small space of time, can I be pregnant? I've read and reread everything about pregnancy after a miscarriage but I want to hear it from actual people, not just Google. Am I pregnant or is this just old hormones? Thanks xx
