Switching pill, protected?

[nexus-13]

I was on progestogen only pill, took it everyday usually exactly in time but then I changed 3 days ago to (don't know it's nickname sorry) levonorgestrel ethinylestradiol and had unprotected sex. Do I need the emergency contraceptive?

P.S day after period so I know chances are silmer

I was the other way round - first I was on combined pill Microgynon then later on single hormone pill Cerazette.

Online I found this about Microgynon -" ideally, you should start taking this pill on day one of your menstrual cycle (the first day of your period). This will protect you from pregnancy immediately and you won't need to use any additional methods of contraception. If necessary, you can also start taking it up to day five of your cycle without needing to use additional contraception when you start. However, if you have a short menstrual cycle (with your period coming every 23 days or less), starting as late as the fifth day of your cycle may not provide you with immediate contraceptive protection. "

Good luck in figuring out what's the right thing to do.x
