Pregnancy tests simply "look" for the presence of a hormone that is present when a pregnancy has occurred. After a miscarriage, a pregnancy test may remain positive for a while until all of that hormone has disappeared below the level the test needs to be positive. A blood (serum) pregnancy test (that you can obtain at a physician's office) can tell about how far along a pregnancy is, and this can be compared to how far along the person should be; the test results will drop in number over time if a miscarriage occurs until it reaches 0. How long it takes the hormone to leave the system is highly variable from several days to several weeks. Hope this helps! Dr. B.

How many weeks after miscarriage can you still get a positive pregnancy test and bleed for?

Some say 5-6wks, but it is safe to wait 60 days before you take a pregnancy test and expect accuracy.

How long after a miscarriage will a pregnancy test still show positive?

It depends. I know this is likely not what someone who is hoping to be pregnant after a miscarriage wants to hear but there isn't a definitive answer since it depends when the miscarriage happened (how far along was the woman?) and also how long it takes for the hCG (the pregnancy hormone detected by pregnancy tests) to leave her system. If a woman is wondering if a positive test is indicating the hormones left by a miscarriage or is a sign of a new pregnancy, she should go to her doctor or midwife for a quantitative (not qualitative) blood test or an ultrasound. A quantitative blood test will measure how much hCG is in her system while a qualitative blood test will do the same thing a urine test does -- say whether or not there is any hormone there. An ultrasound will examen the contents of the uterus to see if there is an embryonic sac or missed particles from the miscarriage.

Does pregnancy test say positive if you misscarriage?

Yes it can. hCG can take 24 hours to a month to leave your system completely depending on how far along the pregnancy was and why the miscarriage happened. If you are unsure if you had a miscarriage or feel that you may still be pregnant consult your Dr as soon as possible.

Does physical activity causes miscarriage?

No, exercise is very good for you during pregnancy and does not cause miscarriage. Some say it does but that is a myth.

If you had a miscarriage 6 weeks ago at 6 weeks and have yet to have a period are having pregnancy symptoms and took a test that was positive could you be pregnant again?

I would say you are pregnant again. It is easier ro get pregnant right after a miscarriage. I would go see a doctor to confirm the pregnancy as soon as possible

How long do you have to wait for a pregnancy test to show if you are pregnant?

Read the box of the pregnancy test? I'm just taking a wild guess here but I'm guessing minimum 30 seconds and maximum 2 minutes? But just read the box on the pregnancy test and it should say how long on there.

What does it mean if theres no heart beat on your ultrasound but pregnancy tests say you are still pregnant?

It can take weeks until the test shows negative after a miscarriage. The hormones takes time to catch up.

Can a low sprem count make a home pregnancy test say negative?

Sperm has nothing to do with a pregnancy test. A pregnancy test is done by a woman to find out if she is pregnant or not. She pees on it and it detects the pregnancy hormone.
