help please

i’m a teenager and last month i had sex a lot without a condom. probably about 5-6 times but the guy pulled out every time and one of the times he got me plan B just in case. It’s been a month and i have feelings like i’m going to throw up but i don’t which i’ve never had before, i got very sick, my boobs hurt and i’m behind on my period by 2 days. Do you think i’m pregnant and i don’t know what to do because my parents can’t find out and i don’t have any money. i don’t know what to do and i’m freaking out.
