My Name is Poppy

im 14 years old

on monday the 11th i got my period

and it finished on the 12th. it was blood but it wasent heavy tho, my period usally lasts about a week and is very heavy but its never done this before. iv bein very stressed lately, i know this sounds impossable but im showing every single first pregnancy sign. i do have a boyfriend and he and i thought i might acturlly be pregnant but then we realized its impossable because we havent had sex and were both still virgins.

could i be pregnant?, or could it be because im stressing out about this whole pregnancy thing and im trying too move around more because im eating alot? PLEASE HELP
