Is there any way my girlfriend could be pregnant?

So my girlfriend gave me a ha****b through my shorts but her hands did have stuff on them. I guess it was semen, but it would have had to go through my underwear and shorts. She wiped the sperm off her hands into the blanket and there was none visible. She touched plenty of other things like tv remotes, cell phone, car door, etc. and about 45 minutes after the ha****b, she washed her hands with soap and water and she brushed her teeth so a lot of water was on her hands. About an hour or so after everything happened, she fingered herself. Her period was 10 days late the month she gave me the ha****b, which was a little over a month ago now. She was on a medicine that her doctor said would cause her period to be irregular but she's off this month. This month her period is 3 days late from last month and she's been having some stomach cramps. Is there any way she could be pregnant? Thanks
