Pregnant?

So I’m 17 and I’m almost two and a half weeks late. I was supposed to start on the 8th so me and my boyfriend decided to have sex. We used protection but it felt weird and we took off the condom. He thought he finished but didn’t know for sure and is being stupid teens kept going. I’ve been experiencing all the symptoms since the 10th of this month and I’m really scared. I talked to my mom and she said to take a test. But I’m curious if anyone thinks I might be?? All my friends and people I know are saying it sounds like I am. And I don’t know what to do. Please helpppp
