am i pregnant? or uti?

so, i'm 17. I recently lost my virginity October 21. my mom does not know i'm having sex. i don't plan on telling her right now neither my boyfriend and i have been having unprotected sex but using the pull out method (yes i know that's not good nor safe which is why i'm going to stop doing that) but, we had sex the november 2nd, 4th, and 9th without condom. i'm not on any form of birth control whatsoever. A week later, (beginning nov. 14) i've been peeing like CRAZY! i'm honestly scared. i do NOT want to be pregnant. it's like i'll go pee, then 6 mins later it feels like i have to pee again but only a little comes out. i haven't been having any symptoms of pregnancy. i have a cold and scratchy throat but i don't think/know if that's a sign. i've been feeling fine. it was like one day out of the week i felt sick as ever but i believe i felt like that because i kept overthinking and stressing myself about this. are these signs of pregnancy? do i just have an UTI? what do i do? my period is supposed to be here around November 25th. i'm trying to be patient but i'm freaking out. i don't know if i'm just exaggerating which is making me stress out and get sick or what. some one help
