In brief: Takes 6-12 days

Yes, it takes 6-12 days for the test to become positive.
She should wait at least one week after intercourse before doing a pregnancy test. If it is still negative after 2 weeks, you can rest assured she is not pregnant from any sexual encounter from at least 2 weeks prior.
