Once me and my girl friend was in a room. She gave me a blowjob with hand. The sperm fell on her fingers.
WILL THAT LEAD TO PREGNANCY??
Now it is right 30 days after it. She has missed one period in between. What happened?? Please help me... Will this happen? Is there any chance of she being pregnant?

If she becomes pregnant based on your story, and claims it is yours, I would definitely ask for a paternity test!! There is no way for a woman to become pregnant from sperm just sitting on her fingers. It can not be "absorbed" in through the fingers.

I have to ask... how old are you?

If you're THAT unaware of the physiology of sex and the method of pregnancy... I'm going to be brutal and say,

DON'T HAVE ANY SEXUAL ACTIVITY UNTIL YOU LEARN.

It's always scary when a girl misses her period but if she is in her teens than having an irregular period is normal.
Unless your girlfriend stuck her hand down her pants with the sperm on her hands, there is prob no way she is pregnant

All right so please take this as nice as u can, now why is this so hard to understand? Unless the sprem went inside of her vag. She can NOT get pregnant! And if u all are so under educated u need to get some birth control and a condom! This is almost as bad as the pink chick or what ever she says I had oral sex so I think I got pregnant, ummm no it doesn't happen like that, that's where the saying I should have swolled u came from! So please go to sex ed and then when u understand sex and u think u can make smart chocies then maybe decide being sexuly active but other than that u need to "keep ur snake to your self!"
