Before i get into this i ask for u to please not judge me because i an terrified.

Ok so about a week ago my boyfriend and i had unprotected sex for like 2 minutes. He had to go and i told him that so i got off of his dick. Then i roll over off of him cum goes everywhere. I could swear that he didnt cum in me but he says hes not sure and has no idea. Im supposed to get my period in like two days but lately ive been getting bloody discharge that looks like im ABOUT to get my period. This started a couple days ago on valentines day. I thought i got my period so i wore a tampon and when i took it out later that night it was maybe a third or half full. I havent really bled since, just bloody discharge and small amounts of spotting. I read online this could be sign of pregnancy. Im not able to get a test for like another week but i dont know what to do. My boyfriend knows but im crying and i know i need to get an abortion because my parents will kick me out and i need to finish school and go to college and i just cant have a baby. How do i even pay for abortion without my parents finding out ??? Im so terrified
