AM I PREGNANT??

i'm almost 7 days late in my period , i have an irregular menstrual cycle , had sex , used the pullout method no obvious symptoms of pregnancy aside from cramps , sore nipples and frequent peeing/pooping which are regular for me since my PMS is very very bad. I haven't tried pregnancy tests yet. im still 20 , a graduating student and worse , a Filipino with very strict parents who WILL disown me if ever I'm pregnant.
