Morning after pill

So I have been on the mini pill for 3 months, and it was making me feel terrible, bloated, spotty, no sex drive, made my hair feel greasy 24/7, mood swings, so I made an appointment with the nurse to discuss changing over to something else. I have a phone call appointment today. I stopped the pill 4 days ago and I've felt soooooo much better I wish I stopped it sooner. However me and my partner had an oops moment last night 🤦‍♀️ 5 years and the first ever one lol, so when she calls me I'll be asking for the morning after pill, will I be able to start a new contraception today if I have the morning after pill or will I have to wait now?
