Unsure if I could be???

My boyfriend and I don’t use condoms, I know I know we’re “asking to get pregnant “ which honestly we wouldn’t mind, but the last time we had sex he came right as he was pulling out and isn’t sure if he pulled out in time for none to get in me. Is there a possibility I could get pregnant from this? It’s been a week and I just wanted to know is that enough for me to think about getting a test? Anyone who can help or has been thru this feel free to comment or share your story please!
