Pregnancy

I'm 16 going on 17 (ill be 17 in January) Im a junior in high school and Im worried that my boyfriend of almost a year now (1 year in September) may have gotten me pregnant, we ran out out condoms so we opted for the pull out method (I know stupid me I was in the moment and I know I wasnt being logical and thinking) ever its been about 3-4 weeks since and I havent gotten my period yet, I also found out that i was ovulating during that time. Ive been nauseous a lot and its more in the mornings but haven't thrown up. Im tired a lot but that could just be because of school and I pee more frequently than usual and strong smells disgust me and trigger my nausea. I bought a 1$ pregnancy test at the store and im scared to take it. Im only a couple days late. Should i wait a few more days then take the test? I really need help guys please dont judge me by my age.
