Help! In waiting room for smear test

[FlipItAndEsreverTi]

And I completely forgot about it until they phoned me this morning to remind me. I had unprotected sex last night. Is that really bad? I'm mortified that they're going to find semen up there. Is this really bad? Do I need to say something?

Panicking!!!!

Quick Google came up with this:
Having intercourse without a condom the night before a Pap will not make a normal Pap smear abnormal, but it might obscure cervical cells so that it cannot be accurately read.

Should you cancel if you “forgot” the night before? Realistically, after waiting two months for an appointment, asking for the afternoon off work or desperately needing a refill on your birth control pills, it may not be practical to take a pass. Be sure to mention to your gynecologist that you had sex, and be aware that you may get a call back if the Pap can’t be read accurately.
