Pregnancy Test Faint Positive Then Negative Then Positive Again
It is possible to have a positive pregnancy test issue and not actually be meaning – despite many people telling you otherwise. It's called a imitation positive – and while it's not common – it does happen (and we know it can be seriously disappointing if you're trying to conceive ? )
Information technology can exist for a number of reasons: maybe you were meaning just are no longer, or mayhap there was a fault with how the test was done / the test was out of date.
"A false positive result is very rare," explains midwife Anne Richley of Northampton General Infirmary Trust (NHS), "but may occur for a few possible reasons," – some of which nosotros've mentioned above and will go through in this article.
We know they practise happen because at that place'south a off-white flake of chat on this topic on our forum – take New_here, who says: "I've recently taken 4 First Response tests (6 days before [ovulation]).
"They were all positive but so I went and took some other five (different brands) – all negative – so took some other First Response and positive? Went to the doctor's – negative?! So dislocated – could I exist getting false positives?"
What causes a false positive pregnancy examination?
While, as we've said, false positives are rare, they happen occasionally. On our forum, Annie Mac tells us: "I merely want all you ladies who are crossing your fingers and toes to remember that simulated positives DO happen.
"If you do become a positive it is very likely you're pregnant due to false positives being very rare. I was having all the pregnancy symptoms and took a Planned Parenthood HPT examination and BOOM bright positive! Information technology turned out it was false and got my hopes up for nix."
So why do they happen?
False positive pregnancy test effect – reasons you might get one
1. Yous were significant, but you lot aren't meaning anymore
As what happened with New_here above, a pregnancy may initially be detected by an early pregnancy examination, which volition give y'all a positive result. But then, when you test again at a later time, you get a negative issue.
Which one is right? Unfortunately the subsequently negative upshot is more than likely to be the true situation – that you're no longer pregnant.
It doesn't mean the commencement positive test was wrong. It was simply an early on test which detected the first stages of pregnancy.
Sadly, many pregnancies don't make it beyond these first few weeks. Improvements in pregnancy tests mean that they're now highly sensitive and can observe the first stages of pregnancy super early on.
- How soon can I have a pregnancy examination?
A later negative test could mean your pregnancy unfortunately hasn't continued and you've experienced an early miscarriage.
This is also known as a chemic pregnancy – a (slightly insensitive) term which ways that your pregnancy was in the very early on stages and had been detected by a chemical (pregnancy) test, but then hasn't progressed.
- How can I tell if I had a chemic pregnancy?
2. The test wasn't done correctly
If y'all read your pregnancy test later the suggested time, a faint evaporation line may develop. (Got one? Find out what else a faint line on your pregnancy test could mean.)
This is not the same as a positive test. This is why it's so of import to check the instructions for how to use your test correctly.
- Are you taking your pregnancy exam the right way?
iii. The pregnancy exam kit was out of date
If you've had an unused pregnancy test for a long time, check the expiration date on the packaging. These are sensitive chemic tests and need to be in appointment to ensure they're working correctly.
4. You may be having fertility treatment involving hCG hormones
Your domicile pregnancy examination measures the levels of hormone hCG in your urine, looking for the sharp increase in hCG when yous become pregnant.
Some fertility drugs incorporate hCG, and then it'due south wise to bank check this before you test. Clomid, which is a popular fertility drug, does not contain hCG and so does not have an impact on your habitation pregnancy test result.
On our forum, StrawberryGirl went to her doctor to find out more. "I spoke to the doctor when I couldn't believe that I was pregnant.
"You very, very rarely can become faux positives though this can happen if you have been on fertility treatment."
5. Yous've recently given birth and your hCG hormone levels are still loftier
StrawberryGirl goes on to say that the physician told her when you take a baby your levels of hCG may still be higher than normal. "You volition also become a positive merely after y'all have given birth as the hormone hCG still in your arrangement," she reveals.
So, yous're testing soon after giving birth, talk to your doctor.
half-dozen. It may indicate an unusual medical condition
It's important to know that this is very, very rare. All the same, there are certain illnesses which cause an increase in hCG, such as trophoblastic illness or islet-cell tumours. If yous're at all concerned, talk to your GP.
If yous're worried because you can only see a very faint line on your pregnancy test, just have done everything correctly, this sounds like a positive result.
- I've got a very faint line pregnancy test result – and so am I pregnant or not?
If you remain unsure about whether or not you are pregnant, do visit your GP who volition test over again and be able to give yous advice on what to do next.
