Have any of you ever had a false positive on a pregnancy test?

I have a verrrrrry faint blue positive line on one of the + - test but I don't see how I could be pregnant as I have an IUD. My period is not really due until tomorrow (don't ask why I'm taking the test in the first place). What do you think? Positive or is it just an error on the test?Have any of you ever had a false positive on a pregnancy test?
False positives are rare. Here's some info:





.False Positive Pregnancy Test


Question: When is a false positive pregnancy test possible?





Answer: In general if you have a positive pregnancy test that's a clear sign that you are pregnant . A false positive pregnancy test is a positive pregnancy test even though you are NOT pregnant. A false positive pregnancy test happens rarely, but can happen both with blood and urine tests, though in each case, the causes can be slightly different.


Before you make the diagnosis of a positive pregnancy test make sure that you followed all instructions. Most manufacturers suggest to read their test after 3 minutes and to NOT READ it after 10 minutes. Once you have a negative test after 3-5 minutes THROW OUT the test. Any positive test appearing only well after that time is inaccurate and cannot be considered positive.


False positive urine tests can also occur under the following circumstances:





Fertility treatment: If you receive shots of hCG or gonadotropins (for example, Pregynl, Profasi, Pergonal, APL) for ovulation it's posible to have a positive urine or blood pregnancy test for two to three weeks after the shot and not be pregnant. A rising blood hCG level usually indicates a pregnancy.


Evaporation line. If you read the test after the suggested time has passed.


Chemical pregnancy


Certain rare medical conditions such as trophoblastic disease, islet-cell tumors


Some drugs like Methadone, chlordiazepoxide, or promethazine can give a false positive pregnancy test


The most important false positive blood test is a 'phantom hCG tesHave any of you ever had a false positive on a pregnancy test?
Hi it does not matter how faint the blue line is you are pregnant and the IUD is not 100 percent you will need to go to your doctor they will want to do a scan first then remove the IUD but be warned you could lose the baby because of the IUD.


P.S Good luck hope you get what you want Hun
more likely to have afalse negative than a false positive, remember no bc method is 100% Good luck to you!!!
i got a postive result when i wasn't really pregnant but it is very rare....anything is possible though i think you should talk to your doctor.....oh and you can get a positive when you have a chemical miscarriage which happens actually quite a bit and you just go on to have a regular period you don't even know you miscarried.
I had a false positive every time I took a test. My doc said that it was due to a hormone balance that was higher than normal. I don't take at home tests anymore, they alwasy read positive. I go to the doc for a blood test, (my husband and I are trying to concieve, which makes it false hope too)...If you have an IUD, chances are that the results are acctually negative...but if you are concerned, you should go to your doctor.
there really is no such thing as a wrong posotive...only a negetive on those tests....i suggest doing another one
There is no such thing as a false positive, only false negatives. The blue line means there is some HCG, pregnancy hormone present in your urine. You only make that if you are pregnant.
the blue line is a confirmation that the body has produced some of the HCG (pregnancy) hormone. It could be a sign of an early pregnancy, which isn't necessarily to last. Also with an IUD a fertilized egg can implant itself at an ovarian tube. Check again in a week, especially if you have other pregnancy related symptoms. You might also then want to contact your OB/GYN for further evaluation if it shows still positive then.





Good luck
i did have a false possitive once, the times i really was pregnant they didnt work. had to have blood test done.
Wait. That's really all you can do - anything is possible - stranger things have happened.
I'm not accusing you but street drugs can cause a false positive. I knew a girl who took 5 tests and everyone was positive- a blood tests showed she was not pregnant. She was/is a drug user.
YEs my wife.
usually that means positive, try it again in a week or so, or now if you are really anxious
It can happen, I have heard of it happening, but its rare.
