how early can i have a pregnancy test

i had unprotected sex with my husband yesterday morning and i'm due for my period next week, how early can i have a pregnancy test?

Way to early you have to wait at least 3 weeks from today before it will even be right. Are you trying to get pregnut? good luck if you are.

If your period doesn't come on the day it is due then you can test. If the test shows a negative but your period doesn't come then wait a few days and try the test again

First of all, your information is incorrect.
BUT if she has normal cycles and she is supposed to start in one week then she would have ovulated about 1 week ago making her infertile at the time she had intercourse. So to her... I wouldnt be concerned with the possibility of being pregnant as an outcome of having sex that late in your cycle.... of course some cycles are odd and theres always a small chance for unexplained happenings....
Just dont let it stress you until you have more of a reason to, i.e. actual missed period.
Good luck.

ok so i am 5 days late on my period. The day my period was due and didn't come I took and test and it came out negative. Then two days later I took another and it also came out early. I read online that if you drink to much than it could dilute my pee, because of my dehydration problem i do drink a good 64 oz of water or gatorade (something to that nature) a day, is this a contributing factor?
My friend insisted i make an appt. for a test and my question is if I have had two negative tests already does that mean there is no possibility?
