HELP!?

Taylah
I know I post a lot but I have been laying in bed paranoid for the past hour..
Okay so 4 weeks ago me and my boyfriend had unpricted sex because it just kind of happened and we didn't really think about protection and he is allergic to latex so we just kind of went along with it... we did it for a little bit but he pulled right before he ejacated and he can feel right before he does and even if it's a tiny bit and I had only come off my period 2 days before and my period is now 8-9 days late is it possible that I could be pregnant but I'm also not showing any signs of pregnancy... can anyone help me??
