A false positive is very rare but it is possible. It is a LOT more common to get a false negaive than a false positive. The best thing for you to do, is to do another pregnancy test. If the test is still positive then you are pregnant and should see your doctor.

No, eating asparagus should not affect a pregnancy test. However, if you don't read the test in the correct time frame (ie, you wait too long), you can get a false positive.

At 3 weeks pregnant should the test come up positive?

Yes it can come up positive. Usully, the results of a pregnancy test are false negatives, not positives. As these tests get more and more sensitive, it is definitely possible that it can correctly give you a correct positive reading at three weeks. I'd recommend a visit to the physician as soon as possible for a more accurate determination of your status and taking care of the pregnancy. 19 years ago my pregnancy was detected at three and one half weeks, so I know these tests are able to detect pregnancy very early on in some women.


You have gotten 3 positive home pregnancy tests and 4 negative Is it possible you are still pregnant only had a 3 hr period at most and since then have had strange painscramping. am i pregnant?

It's a fact, you can't get a false positive, but it's very likely to get a false negative! The pregnancy hormone detected in pregnancy tests is at it's strongest in the first urination of the morning, so if your negative results were at a different time, it's likely you weren't far enough along to detect it, except for in the morning. GO SEE YOUR DOCTOR!!! =)
