i might be pregnant.

Well.I'm only 14 and yes I know that age is WAY to young to have a child. But I want one. Anyways ,my period usually comes around the 1-9 and I had it normally this month. I had unprotected sex like 2 days after my period,and a couple more times throughout the month. Now I'm having my period again, its 2 weeks early. Could I be pregnant ? Help. thank you !
