I think I could be pregnant

My last period was in the middle of November. The month of December was my last month being on the pill because my boyfriend moved away & we both agreed for me to stop taking it. We are still together & he was here for the past week & we had unprotected sex. Every time he came, he pulled out. Although he did, I am still scared I could be pregnant since I have not had my period for two months now. I’m scared to take a test because we are only 21 & I don’t know how we’d be able to take care of a baby right now. What do you guys think? Should I take a test or no?
