How late can a girls period get when shes stressed?

Nah, I'm not that good I'm afraid.

I just never give "straight-up" compliments because they feel half-assed. Like:

"Wow, Ziggy, you are amazing!"

or

"Gee willikers that was keen!"

I have no idea where I'm going with this. <.<

back on topic please.

it could even be sad that .... "u nailed it"

Hey, whats the problem really, just wait a few weeks and you'll notice if she's pregnant. You've been a virgin all your life, so I don't think you should feel a need to jump on the first chance (even though the situation you're in is weird), so all you have to do is wait.

She's pregnant: dump her.
She's not: think about if you actually wanna be with her, then decide if you ought to dump her or hump her.

Even if you find out after you've humped her that she's unfaithful, it's not the end of the world, even though it might feel like it. Just realize that you've taken another step on the "life is a bitch and then you die" path.
