Could a 12 year old girl be pregnant even though she hasnt had sex? I noticed that i'm a bit chubbier then usual and my weight has gone up 2 kgs in 1 month. I havent had sex though. Could I be pregnant?

Being pregnant requires the transfer of sperm from a male into your body. That can happen in other ways than the typical sex act however; by touching with sperm on the hands for example. If you've had absolutely no contact of any kind with male sperm, you are not pregnant.

sorry, but Unless your boyfriend is Really potent, you are are just gaining weight.

There once was a case when a 9 year old went swimming in a public pool, and there was sperm in the pool, and it got in her body while she was swimming.
But, honestly, it could be your hormones, and you're overeating.
If you're worried, you can always talk to your parent/guardian, another relative, or your school nurse.
