Baby name discussions began today... i dont even know if im pregnant yet!

hi.. im gonna say something that im really embarassed about and its something that people will look down on me for but... im 14 and yes i did say 14.... anyway... my boyfriend and i have been together for just over 1 month(yes i know you probably think im a slut (think what u want i dont care) weve had sex twice and he took my virginity and i took his to yeah... any way... seth (my boyfriend) and i are really scared that i am pregnant and ive told a couple of my friends that i know i can trust... and they are all here for me and when i told seth i was freaking out.... and so was he but he managed to calm down really quickly and he started calming me down... ive gone to canberra for the easter holidays while hes stayingg on the gold coast... we talk every day... and today we were discussing baby names... if its a boy he wants to name it bentley.... like the car...
then we had a lightly heated discussion about whose last name we would use.. i want to use his.... but he wants to use mine if its a girl and his if its a boy...

any way im really excited... but im really scared because my parents will massacre both of us... but i think seth will be a great dad and i know that he wont leave me..... and i know that if i am pregnant and i dont have a miscarriage we wont have much money but ill get a job and seth and i will probably split our education and we will do every thing humanly possible to ensure that our baby has an amazing life..

i need as much help as i can get so i would really apreciate it if you could give me advice on what to do

and i am against abortion (unless its incest or rape)
