Can plan b have an affect on fertile window ? If so help ://

I had unprotected sex yesterday & well I forgot I was on my “predicted fertile window” not knowing that I was, I carelessly had sex and took a plan b after. I looked up online since I’ve been experiencing stomach pain and nausea, & well I saw that plan b wouldn’t work if taken on ovulation days. I was hoping maybe I could at least get some answers on here since most of the women on this app have or has experienced what I’m experiencing now. Honestly, I’m also expecting some hate towards my question, so I’m okay with how brutally honest some of y’all may be. I guess moral of my question is, would it still work if I took plan b 2 hours after unprotected sex ? Does my “predicted fertile window” affect the plan b ?
