can you have a false positive with a pregnancy test?

Well the title says it all really. If you get a positive test, can it be a false result?

I know you can have a false negative, because I did last time and it turned out I was nearly 3 months pregnant! (breastfeeding and no period, which is why I didn't notice before).

The thing is I'm not sure if it works both
ways - can you have a false positive?

No you can't get a false positive but you can get an evaporation line. Did you check test within ten mins?

good, I wanted to have 3 children anyway!

I've just done a test, and it has a rather faint line, but it's definitely there!

yes, I checked the test in the right time frame

It looks like I'd better make an appointment with the doctor soon then!

Hi alexpolismum, the circumstances whereby you might get a false positve should be outlined on the leaflet that comes with the pregnancy test kit. I think these circumstances are most rare (unlike false negative which can be quite common) - so I'm sure you are pregnant! Congratulations!

Hello,I dont really know where to start..I have taken 5 tests just because i wanted to make sure the first 4 were right! some of the lines were pale and others not so pale. Im abit confused am i pregnant? I mean i think i am its just the shade of the line that is giving me doubts... Any help would be much appreciated....

Doesn't matter how dark the line is - if it's there within th etime frame on the instructions then it's positive. Depending on the time of day / how much you have drunk you will have different concentrations of hcg in your urine which is why it can look different each test, even on the same brand of pregnancy test. So yes it sounds like you're pregnant!

The test that has a cross instead of two lines for a positive is known for false positives. I think this is the cheaper version of clearblue (not digital). I got one and phoned the manufacturers who apologised & sent me a digital replacement. I hope yours isn't one of these.

deany, that was most certainly a very early miscarriage.

Almost impossible under normal circs to get false pos.

Congrats alex

sorry to hijack but question for alexpolismum

did you have any symptoms with breastfeeding and being pregnant?

Report
alexpolismum · 29/04/2009 20:27

Not really. Or not until I got to the third month and started feeling dizzy going up stairs (this happened with my first pregnancy).

I didn't get sore breasts/ nipples. In fact the whole pregnancy was great, no morning sickness, generally felt better all round. However, this probably had nothing to do with breastfeeding!

bringonthetrumpets - are you breastfeeding and think you might be pregnant?

No. You can get a false negative. The only thing u should be careful of is doing the early Pg tests as they can show you are pregnant - quite rightly - but the PG may not continue and you have your period.

well, I'm breastfeeding and hoping I'm pregnant! haven't had a period since 17 march and many many BFN's. I'm pretty sure that its just due to bf-ds is 7 months. We're currently TTC#2 atm....

I just assumed that everyone had sore nipples and breasts if they were pregnant and breastfeeding. Very interesting to hear actually.

Congratulations btw!

Thanks.

I'm actually in the same position this time as well, as I'm still breastfeeding my second baby. No sore nipples or breasts as yet. Maybe I'm just lucky!

good luck with ttc!
