How possible is it to get a positive when you are not pregnant?

[TrinityTheProgressingRhino]

my sister has been trying to get pregnant since her 8 yr old ds was about 3

she has tried chlomid (sp?) and is having trouble
BUT she had 2 positive pg tests today
she wasn't even testing to see if she was pregnant!
she refuses to get excited until the doctor confirms on wednesday
Do you think she is?

I think the pg tests check for the HGC hormone which is definitely not there unless you're pregnant. False negatives are commoner than flase positives as far as I know but someone with more experience will be along, I'm sure.
Sounds to me as if she is, though. Congrats!

is clomid a hormone drug? Some hormone drugs can give you false positives. But if not highly unlikely to get false positives

I'm not sure she is taking the clomid anymore
I'm not entirely sure what it is either
I know that she has to take something to make her ovulate though

Hmm, she doesn't live near me at all and I forget what exactly she is trying at the moment
I thought she had taken a break from trying to conceive though, maybe thats why she got pregnan

Fingers crossed for her - do let us know!

yeah I think its the drug that makes you ovaluate that can give you false positives. Has she got any preg symptoms?
