STI testing

If i didn't have it, and he didn't have it, where did this STI come from?!

Kayla
asks:
My question is, I was tested for Gonnerhea and Chlamydia at the end of April of 08 and I was negative. I just got another test done when I was refilling my birth control three months later and came out positive. I know I surely have been faithful, and so has my partner, but we can't understand where it would have come from between the last test and this test....

Do I really need a pelvic exam?

Tori
asks:
Why is a pelvic exam really necessary? I am sexually active, but my boyfriend and I have only ever done anything sexual with each other, and neither of us have anything. I've asked this question to other people and they always say that "You don't KNOW," or that I shouldn't just take my boyfriend's word for it....
