Could it be possible??

Okay so I had unprotected sex on Jan 15th then took plan b on the 17th but I was supposed to start my period on the 15 and never did but I started my period on the 22nd but I know having sex can mess up your period so can plan b. And my next period should be here in 9 days. But is there anyway I could get pregnant after all of that?
