A couple of months ago I took a clearblue digital pregnancy test. It tested positive pretty much right away. It states the result in words so I did not misinterpret a line or something. We were incredibly happy. The same day I took a pharmacy home brand test which tested negative. The day after, another clearblue digital negative. Three days after that one, a negative one at the doctor's. I am not taking hormones and have not been pregnant recently so that rules out the two situations in which you could get a false positive according to their own info. I have heard of false negatives, but never heard of anyone with a false positive. Has anyone else had this problem?

I have come to the conclusion it must have been a chemical pregnancy, however I took the test a few days after I had a period that was light and lasted only two days. If it was a chemical pregnancy I should have had my period AFTER the positive test, right?

Thanks for your advice to go see a physician but I did several months and periods ago. I am pretty confident that if I am pregnant, it is a more recent one, or I would have had symptoms by now.

Those home pregnancy tests are extremely accurate. You assume the test is correct until another proves it wrong.

Could I have a false positive? Check out The Truth About False Positives for an in-depth look at false positives. Essentially, it is possible, but it's unlikely. If you get two lines, you're most likely pregnant. Exceptions: if you have been taking certain fertility meds with hCG, the test may be picking up the hCG from the meds and not an embryo. Also, some tests develop "positive" lines after the time limit. You should NOT read the test after the time limit (usually 10 minutes, but check the directions that came with the test.) Yes, this means you should throw the test away and NOT dig it out of the trash in three hours to see if a line magically appeared. And, if the "positive" line is gray or looks like a "dent" in the test, it is an evaporation line and not a true positive.
Lastly, if you have been pregnant recently, it's possible that the test is detecting residual hCG. However, if a pregnancy ends early on, it's unlikely that hCG will remain in your system very long, so most women have nothing to worry about here. (It's extremely common for women to conceive immediately following an early miscarriage; the body is "primed" for pregnancy, so to speak, and elevated progesterone left from the miscarriage gives the next embryo a great shot at a healthy implantation. So, most women really are detecting a new pregnancy.)

Your body gets a hormone called HCG when you are pregnant. Most hpt's only register a positive result if there is an HCG level of >25 in your urine. Every woman is different and the values are of a very wide spectrum...for example
9-60 equals to 3-4 weeks pregnant.
Could be that one or more of the tests are more or less sensitive then the other. But if you are truly not pregnant, then you got a bad test. and the doctors office usually has on hand the more sensitive test. If you are still not sure, ask your doctor for an HCG blood test. This is the most accurate and can read a result of anything greater than 2.

My sister in-law was in this same situation. For her, it turned out that she wasn't pregnant. EPT is one of the most accurate HPTs. It can detect very low levels of HCG. The generic tests are famous for false results.

Its very unususal to get a false positive as the home kits are 99% accurate, false negatives are, as you say much more likely.
Sorry you were dissappointed.

I took 3 EPT's last month & they all had a very dark plus mark (very, very dark). Well the doctor did bloodwork & it all came out negative & I got my period about a week later.
So no, hpt's are not that accurate.
