I took an HPT when I was exactly 4 wks, and it was positive. You don't HAVE to be 6wks, but it MAY take that long for the test to show positive...it just depends. Alot of those symptons are all symptoms you get right before your period as well as in early pregnancy...so you might be pregnant, you might not. You can also fake your body out and you *think* you have those symptoms when you really dont, you're just freaked. I would take another HPT just to see.
its a possibility u could b. take a hpt
