some show up to 9 days before your missed period so you'd still have to wait about 3 weeks from the time you had sex, but chances are very high i had sex on my ovulation week and got pregnant the first time that i didnt use protection lol
yeah u have to wait longer than week....
Depending on your body chances should be high. Sperm last in the body up to 5 days. Good luck. They are racing. : )
I'm pretty sure you will have to wait longer. Nothing will show you that early. You have to wait till you miss your period.
