Possibly pregnant 7 weeks after d&c?

I had my yearly physical appointment today. I had a D&C back on March 9 due to a MMC. I still haven’t had my first period since the surgery. And we only DTD two times since then. But today the dr ordered a urine test and it came back positive. She also ordered blood work. Could I be pregnant 7 weeks after d&c before getting period, or is it residual hormones?
