Can you get a positive pregnancy test 2 weeks after sex?

Pregnancy test: A home urine pregnancy test won't turn positive until 10-14 days after conception. Using the 1st urine of the morning will concentrate the beta-HCG hormone in the urine. So it should be accurate provided it's been longer than 14 days.

Yes.... but: that is the general limit of when it starts to be positive and you'd have to conceive right about the time of intercourse (t would be 2 weeks gestation; tests often begin to be positive at that point) and pretty reliably positive 1-2 weeks after than.
