It could when you test too early in your pregnancy. Modern tests however have a 99,8% accuracy rate, so in most cases you should assume you are not pregnant.

Can an expired pregnancy test give a false negative reading Even if it's only 1 year expired?

Yes it can. Any pregnancy test can give a false negative (not picking up on the presence of the hormone hCG (human Chorionic Gonadotropin)) however they will not give a false positive (The hormone will only be there if you are pregnant) An expired pregnancy test will be even less accurate.


How soon do you know you are pregnant in your tubes?

Pretty soon; an ectopic (tubal) pregnancy is very painful, and you would need to go to the doctor as soon as possible; an ectopic pregnancy can cause damage or even death.


Can you be pregnant even though a blood test came back negative 14 days after insemination?

It's highly unlikely. Blood tests measure HCG levels, and an hCG level of less than 5mIU/ml is considered negative for pregnancy, and anything above 25mIU/ml is considered positive for pregnancy. If you still do not have a period go back for a repeat test to see.


If you take a pregnancy test and its positive and the next 3 are negative but the next day take 4 more and the first one is positive and the rest are negative what are the chances of being pregnant?

A negative test could also be the result of a phantom pregnancy. A phantom pregnancy is where you basically fool your mind and body into thinking it is pregnant. You will still experience pregnancy symptoms but you are not actually pregnant; it is al psychological Some women have even been able to lactate during a phantom pregnacny. The causes of a phantom pregnancy are either paranoia of being pregnant or having an extreme desire to become pregnant. There are several things that can contribute to a negative pregnancy test even if you are pregnant. Some medications can give you a false negative, the timing of the test can affect the results. If you did not follow directions properly; if you let the test sit for too long the results may read negative after a while. It is important to read the results within the amount of time given on the instructions of that particular pregnancy test you bought. If you did not perform the test properly (example: you drank a lot of fluids before taking the test, which can dilute your urine). Etc.On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.To ensure the best results: Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results Take the test no more than 1 day before expected period. Although some test say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low. urinate for as long as possible on the foam-like strip Check the results in the window frame of time suggested by the instructions of the pregnancy test.


If you have a tubal pregnancy will it read on a pregnancy test?

Most pregnancy tests test for the presence of Human Chorionic Gonadotropin (hCG) in the woman's blood or urine. Ectopic pregnancies are usually picked up by home pregnancy tests however it is possible that do to lower levels of hCG that sometimes result from ectopic pregnancies you could get a false negative. Ectopic pregancies can potentially become very dangeros, if you suspect that you may have an ectopic pregnancy even if a home pregnancy test is negative, it would be wise to see a physician.
