How long after a chemical pregnancy will a HPT still read positive?

It typically takes about 1-2 weeks for the pregnancy hormone hCG to leave the body after a chemical pregnancy, so a home pregnancy test may still read positive during that time. It's recommended to follow up with a healthcare provider for confirmation and monitoring.


Can you get a negative urine pregnancy test even if a blood test comes back positive?

No, a urine pregnancy test measures the same hormone (hCG) as a blood test, so they should typically give consistent results. If a blood test is positive, a urine test should also show a positive result.


Does dettol work as pregnancy test?

No, Dettol does not work as a pregnancy test. Pregnancy tests detect the presence of the hormone hCG in urine, while Dettol is an antiseptic liquid that is not designed for use in pregnancy testing. It is important to use a specific pregnancy test kit for accurate results.


If water is mixed in urine of pregnant woman it give positive result or not?

Mixing water with urine from a pregnant woman will not affect the accuracy of a pregnancy test result. The presence of hCG hormone in the urine is what determines a positive pregnancy test result, not the addition of water.


What is the difference between a chemical pregnancy and miscarriage?

A chemical pregnancy is an early pregnancy loss that occurs shortly after implantation, before the pregnancy is visible on ultrasound. It is usually detected by a positive pregnancy test that later becomes negative. A miscarriage, on the other hand, is the loss of a pregnancy after the embryo has implanted and is visible on ultrasound.
