Trying for a baby

Hi Gals

So it’s my first time trying to become pregnant I’m in an 8 year relationship. Last month I was let down so tried again this month, periods are not due until first week of July but I have no patience and I’m dying to know. How soon does it take for a test to show positive? If I done a test 1 week after the first unprotected sex and it was negative would that be legit? Last Saturday was the first time we tryed this month and everyday 2nd day after.. I really have no patience 😣
