Plz help me! i think i can be pregnant?

hi people. you are probably gonna think im lying but i just really want you guys to help me out. k well im only 14 years old and ive had lots of boyfriends but we never really did anything. then i really liked this hot guy and i told this girl and she asked him out just to be mean! she had with him apparently and she told like, the whole school. she is sooo mean to me and she even knows that i liked him and when i told her she was like, ewww hes ugly. and so after i like, wore really revealing clothes and i flirted with him a lot and i purposefully like, dropped stuff to pick em up real slow. yesterday i asked him if he thought i was y and he said yeah and he ALWAYS stares at my . so like, i got him to like me i guess and yesterday we were hugging and we started making out. she didnt walk by so then while we were in cl (we only have two cles with all three of us togather) we happened to have a substitute so i made sure to sit somewhere next to her and we started making out. she saw and they broke up, YAY! but like, then we had last night and i feel bad now. we didnt use a condom or anything and i had myperiod ten days ago. can i be pregnant? im really scared. oh, and we had again this morning and probably tonight all with no condom cuz he said that condoms hurt him. but this morning we did it in the shower cuz i told him that im scared of getting pregnant and he told me that water washes the sperm off. but now the whole school knows that im having and i already get in trouble a lot. (its always for being disrespectful or for pda though) so what do i do??? btw, im on my friends account and she already knows so, ya. thanx!
