Positive Pregnancy Test After D&C

Why the Test Is Still Positive

A positive pregnancy test after a D&C does not by itself show that something is wrong. Home pregnancy tests detect human chorionic gonadotropin (hCG), which falls after a pregnancy ends but can remain detectable for several weeks after an early loss. The starting hCG level affects how long it takes to fall below a test's detection threshold.

Many home pregnancy tests detect hCG at about 20-25 mIU/mL, though sensitivity differs by test. A higher starting hCG level generally takes longer to fall below a test's detection threshold.

The Expected Timeline

The timing depends on the pregnancy and the follow-up plan. After expectant or medical management, NICE recommends a home pregnancy test three weeks after the miscarriage and clinical review if it is positive. After a D&C, follow your provider's plan for an ultrasound or blood hCG test to confirm that the tissue has passed. A non-pregnant blood hCG level is generally below 5 mIU/mL.

After a later loss, hCG can take longer to fall. After a molar pregnancy, follow the specialist's serial hCG monitoring plan rather than relying on a fixed number of weeks.

When a Persistent Positive Is a Problem

A positive test three weeks after expectant or medical management warrants clinical follow-up. After a D&C, follow the timing your provider gave you; a test that was falling and then rises again needs assessment. Home-test line darkness cannot measure the hCG level or reliably show its rate of decline. The clinician may check for:

Retained products of conception (RPOC). If tissue remains in the uterus after the D&C, that tissue can continue producing hCG. Symptoms include prolonged bleeding, persistent cramping, and hCG levels that plateau rather than decline. A follow-up ultrasound can confirm RPOC, and a repeat procedure may be necessary.

New pregnancy or another cause of rising hCG. Ovulation can return as early as two weeks after an early miscarriage, so a new conception is possible before your first period. A new pregnancy is one possible explanation for rising hCG; retained tissue, ectopic pregnancy, or molar pregnancy also need clinical assessment.

Tracking Your Decline

Your provider can use serial quantitative hCG blood tests, ultrasound, or both to confirm that the miscarriage is complete. A quantitative test measures the hCG level; a home test only shows whether hCG is detectable.

If your provider did not schedule follow-up, contact them to ask which check is appropriate for your procedure and symptoms. Weekly blood draws are not required for every uncomplicated D&C.

Do not rely on home-test line intensity to judge whether hCG is falling; follow-up blood tests or ultrasound can assess that.

The After a Miscarriage toolkit includes a physical recovery timeline that tracks hCG clearance alongside other recovery markers, so you can bring organized data to your follow-up appointments.
