How long before you can take a pregnancy test?

Do you REALLY have to wait until your first missed period?
Its been a week, and I know its probably too early to tell.. how soon before any of you took a pregnancy test [and was it accurate]?

you need to wait until a minimum of 10 days AFTER conception. until then you don't have enough of the hormone HCG in your body, this is what maintains a prgnancy...

No you can take it now im pretty sure.
at least, thats what the comercial says

no you can't take it now it's too early. you have to take it after your first missed period, or you can get that first response pregnancy test and take it 5 days BEFORE your missed period, which is the earliest you can take one.

but either way, when the time comes you should take 2 to be sure. false negatives can sometimes happen but false positives are rare.

There are some pregnancy tests that you can take 10 days after the time that you think you conceived. I never used them though so I'm not sure how accurate they are.

Thankyou guys
