PID

[DollStar]

So, new boyfriend, but 3 weeks after having intercourse, I get this pain - like period pain. Go to nurse and she sends me to the sexual health centre where I had all the std tests. Clamydia, the works. Anyway, these have come back clear but she gave me two antibiotics as she said I could have Pelvic Inflammitry Disease.

My question is, if I have tested negative for STD's would intercourse without a condom be enough to give me PID? Im a bit bemused with it all, should I tell him to get tested??
