There are a few factors that can result in a false positive. Most of the time though false positives are rare! I recently experienced this. I have 4 children and have never had a false positive! My test never showed up unless I was pregnant. I recently had 5 tests show a faint positive and went to the doctor for blood test which was negative. I was told that a cyst on your ovaries can sometimes make a test appear positive (false positive). Other factors include chemical pregnancy. This is one where everything develops as though you are pregnant, except for the baby. If you are on any medication that contains the pregnancy hormone (HCG), this also can make your test turn up positive. It is best to have a blood test done by the doctor to totally insure you are not pregnant.

If you are 3 days late no period and faint positive what does this mean?

You are pregnant! At three days late your body is not producing enough HGC to make the pregnancy test show a definite positive. Pregnancy tests rarely give false-positives. They may give you a negative answer and be wrong. But they rarely give you a positive (even if it is a faint positive) and be wrong. Taking the test again in a few days will show a darker line. Congratulations!

Can asparagus make a false positive pregnancy test?

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. Also, sometimes a false positive happens for no apparent reason - this is inherent in a home pregnancy test although most manufacturers work to reduce the possibility of this as much as possible.

Are you pregnant if you had little to no bleeding and had a 1 positive pregnancy test and 2 negative pregnancy test?

It is rare that you will get a false positive. Make sure you are reading the directions correctly on the box for each pregnancy test you take. They need to be on a flat, dry surface and left alone until the time limit in the directions. If you had some bleeding/spotting this could be implantation bleeding which is common in your first symptoms of pregnancy. I only tested positive on a Clearblue pregnancy test. No other test would give me a positive. So it could also be the brand you are using. I wouldn't recommend dollar store pregnancy tests. Pregnancy tests aren't cheap, but you get what you pay for.

Is 15 days after possible conception too early to get an accurate result from a pregnancy test?

No, some pregnancy tests say they can give you an accurate result 5 days before your missed period. If you get a negative result, it is best to test again a couple days following your missed period to ensure you are in fact not pregnant. If you get a positive more than likely you are pregnant as it is more likely to get a false negative than a false positive. If you do get a faint positive and are still unsure, take another test a couple days following your missed period and if that test is positive call your doctors office and make an appointment. Good luck!
