ok my period usually lasts 5 days and would start on the 3rd or 5th of the month starting in october this year it changed to be the 8th of the month, i have not had sex but have been fingered which i have heard u can become pregnant off of.i am not on any form of birth control. i had been gaining weight, i cant remember if i gained weight before or after being fingered however i eat cafeteria food everyday so that may be why. now in november my period was on the 10th and it was short and lighter than normal. i have gained 10 pounds now. I also am a serious athlete and exercise everyday. Now in december i still havent had my period and it is now the 12th. Im only 16 so its hard to get a pregnency test and i dont have much money to spend.
what is the likliness i could be pregnant
