Can I be pregnant if a boy fingured me and I was not looking could he of been wanking at the same time and then used the same hand which could have had sperm on it and then fingered me?I've also missed 3 periods.

No not possible. Need penetration for pregnancy. Go to your doctor, there are many other reasons for missed periods.

Go to doctors, get checked it only takes a small amount of sperm to get inside of you , take a pee sample to docor who cannot tell anyone your info not even your parents don't worry they will guide you and tell you all your options.

My answer would be no on the fingering question. But, if you've missed 3 periods... Could something else have happened? Where in you in the dark, drunk or high, and can't quite remember what happened? If it was very dark, maybe he slipped in while you still thought it was a finger? Get a test, because by three months, it will show up on the test. Also, if your boobs are sore and swollen, you may really be pregnant. That's one of the more obvious signs.

Wow. Are you on any form of birth control?? If not, I suggest that be your #1 priority... right after you get a pregnancy test. Don't tempt fate.
