I need opinions! i'm stuck!!!?

My boyfriend and I had sex last week and i might of gotten pregnant, im not sure... so i took the morning after pill just to be sure... those things were expensive! now yesterday he told me he might of done it again... i got so mad at him... the reason is because the first time i could understand cause i just started taking the birth control pills but a 2nd time! come on!! i can't afford to get the pill ALL THE TIME... if i remember right, it cost me about 50-60 dollars. and i paid it cause i didnt know i had to wait a month for the birth control to start working, but then i told him and he didnt listen! ugh! what are your opinions??? I need serious answers please... (i know he should of used a condom and everything but w/e... its already done)
