Am i pregnant. (Cross posting in groups)

So on June 4th i was having sex with my boyfriend, and he took the condom off with out me knowing, once i did notice i made him stop, it was my second fertile day with 15% of pregnancy. He swore he didnt cum. My period is one day late and im sort of freaking out a bit. Usually i have cramps a few days before my period but theres been nothing. I went to the sexual health clinic and took a pregnancy test, it came back negative, they said if i still dont get my period in six days, then to come back and retest. Ive had barely there cramps. Im really scared. I already know that if i am pregnant then ill need to get an abortion, i just rather not deal with any of that stuff because i don't know if i can handle it mentally right now, i have to keep it a secret from my mom because of she found out theres no way shed let me get an abortion. Im just so worried. I havent had any of my normal PMS symptoms either.
