We can't say for sure since we aren't professionals, but it's unlikely your girlfriend is pregnant. You got semen on your hands and after a little while, washed and dried your hands. Sperm don't live that long when exposed to air, more so if you washed your hands. It's unlikely that partially putting your finger inside your girlfriend would result in pregnancy.

As it's been said, her period may be delayed by stress, flu or just by having an irregular cycle (it happens sometimes!)

You can wait for your girlfriend to have a period, but if you are that desperate, you can always get a pregnancy test from a pharmacy or drugstore. The results should be accurate given that some time has passed.

It might also help to look into birth control, even if you aren't considering sex. Condoms can be good for preventing sexually transmitted infections as well as pregnancy and there are flavoured condoms for oral sex. And in general, it's good to maintain hygiene (washing hands) anytime bodily fluids are involved.

Hope this helps
