after your period is late (usually) and in the morning!

would it make a diffrence if i took it now???

your pee is most concentrated first thing in the morning, that's why that's the best time to test.

is your period late?

ya

then you should be okay, but i think you should just wait a few more hours and take it in the morning, you have more of a chance of getting a positive. theres no reason to waste a test just to get a negative if you really might be pregnant.

you'll get the most accurate result if you test first thing in the morning, or if you don't pee for about 4 or 5 hours & then test. you want your pee to be really concentrated because that's when (if you are pregnant) there will be the most amount of the pregnancy hormone in it.
