A positive pregnancy test followed by bleeding can feel confusing and upsetting. One possible explanation is a chemical pregnancy—a very early pregnancy loss, usually before five weeks, before a pregnancy can be seen on ultrasound.

The pregnancy produces enough hCG to give a positive test, but then stops developing and hCG levels fall.

Possible signs include:
• A positive test followed by a negative result
• Bleeding around or after your expected period
• Cramping or bleeding heavier than your usual period

However, bleeding alone does not confirm a chemical pregnancy. Bleeding can also occur in an ongoing pregnancy or an ectopic pregnancy.

Contact your healthcare provider if you bleed after a positive test. Repeat hCG blood tests and, when appropriate, ultrasound may help clarify what is happening.

Seek emergency care for severe or one-sided abdominal pain, shoulder-tip pain, fainting, or heavy bleeding.

Early losses often involve chromosomal problems and are usually not caused by anything you did. One chemical pregnancy does not mean you cannot have a healthy pregnancy in the future.

Your feelings matter, even when a loss happens very early. If losses repeat, discuss further evaluation with your healthcare provider.
