help please ladies! PREGNANCY SCARE

Hey gals, I had unprotected sex on my last fertile day ( unsure when I ovulated but presuming it was a couple of days before unprotected sex ) he pulled out and does not think he came in me and if he did it was virtually nothing. I took the morning after pill the next day however once I had taken it I reading the box that in order to stop pregnancy this particular pill stops the release of an egg, if I had already ovulated does this mean that the pill I took was pretty much pointless, my next normal period should be in 4-7 days and as of tomorrow it has been one week since I took the morning after pill and still haven't gotten a period ( the pill I took can delay periods )
What do you girls think just need a little advice as im quite nervous and have a lot on my mind already, thanks! ❤️
