Could I be pregnant?

Last week I had unprotected sex while it was my fertile window week and most likely the day I ovulated that day I’m not too sure, the guy pulled out but idk bc I felt when he relaxed inside of me (tmi sorry) he also texted me “ I think you should get the plan b just incase” he then messaged me again the next day asking if I got it and I said yes I got it we’re good, I’m scared because I lied to him about getting it. is their a possibility that I’m pregnant?
