HELP ME PLEASE

Hi, so I had unprotected sex on the 21st of December. I checked back my period app and I was ovulating that day. The next day I got the morning after pill but discovered since I had ovulated it doesn’t work but I still took it incase. 2 days after sex I got the copper coil fitted(nova T). That day I was bleeding and for the past week I have had cramping and some brown/pink discharge. My period is due on the 5th of January. I am wondering if I will still get pregnant or if I have done enough to not to get pregnant and am also wondering if my period will be delayed bc of any of this?

Thank you for your help
