I need advice please

london

Me and my boyfriend bad sex with protection. He normally pulls out when he cums this time he didn't pull out. Condom looked like it didnt have any leaks. Nothing is coming out of me. Because it was the first time a quite nervous and im a big overthinker. Im on day 7 of my cycle and i dont know if i should get a plan b or am i over freaking out. I just need some good advice right now. Thank you
