If i am Pregnant 6 weeks bleeding ultra sound read no baby in womb why test saying positive?

Possible reasons for a positive pregnancy test despite an ultrasound showing no baby in the womb:

1. Early Pregnancy: Sometimes, during early pregnancy, an ultrasound may not be able to detect the fetus. The embryo is tiny and might not be visible on the ultrasound until a later stage.
2. Ectopic Pregnancy: In an ectopic pregnancy, the fertilized egg implants outside the uterus, most commonly in the fallopian tubes. Despite this abnormal implantation, pregnancy hormones are still produced, resulting in a positive pregnancy test.
3. Chemical Pregnancy: Also known as an early pregnancy loss, a chemical pregnancy occurs when a fertilized egg implants but fails to develop properly and is expelled before an ultrasound can detect it. Even though the pregnancy ends early, the hCG levels may still be detectable, leading to a positive test result.
4. Incomplete Miscarriage: In some cases, a miscarriage may not be complete, meaning some pregnancy tissue remains in the uterus. The presence of this tissue can continue to produce hCG, resulting in a positive pregnancy test.
5. HCG-Producing Tumors: Rarely, conditions such as gestational trophoblastic disease (GTD), which involve abnormal growth of placental tissue, can produce elevated hCG levels and lead to a positive pregnancy test without a viable pregnancy.
6. Cross-Reactivity: Some medications, medical conditions, or even certain foods can interfere with pregnancy tests and cause false-positive results. Cross-reactivity occurs when substances other than hCG interact with the antibodies used in the test, resulting in a positive outcome.

It's crucial to consult a healthcare provider as soon as possible if you have a positive pregnancy test but an ultrasound has not shown a baby in the womb. Further tests and evaluations are necessary to determine the exact cause and course of action.
