Dried Semen, Fingering, Pregnant?

Okay, so...I've seen lots of posts about this, but there's just something about having to share your own story. So, here it goes.

My boyfriend ejaculated, he rinsed his hands with water (no soap) and dried them off. He continued to do a couple of non-sexual activities (i.e. - eating, taking his blood pressure, eating again...) And then about forty minutes later, he fingered me. I used an online ovulation predictor, and according to that, I was on my first day of ovulation - so that's a little scary. Anyway, I know that it's definitely a long shot - but what are the chances of pregnancy here? Can sperm live after being in the 'air' for forty minutes?

I don't usually fool around, but as you all know, things can get heated. Unfortunately, I'm a worry-wart and I can't get the possibility of "what if?" out of my mind. So, what are the chances? I'm so stressed out and I'll probably miss my period for that reason alone and the thought of having to buy a pregnancy test makes me want to puke...

Anyway, ANY thoughts and opinions would be greatly appreciated!
