Hello, I'm Ted Manos MD, board certified obgyn. For your information, blood HCG levels are of course elevated in pregnancy. Rule of thumb, the HCG level doubles every 48 hours. If I had a patient with an HCG of 500, it should be 1000 in 48 hours. After a miscarriage, it takes 48 hours for the HCG blood level to drop half what it was. With some retained pregnancy tissue and the d&c you had, your HCG level was probably around(###) ###-#### ***** we do the math, the HCG level would be gone in two weeks. In my experience, HCG levels don't "linger" unless some tissue is still present causing HCG to be detectable. It usually takes three weeks to ovulate after a miscarriage or the d&c. You are probably pregnant. All this information I saw repeatedly over the years that was so amazingly consistent. I hope this helps in your thinking and you should repeat the test about 3-5 days
