Pregnancy chances?

So I have the nuvaring. But because it sticks out a little all the time I'm afraid it didn't work.

We wore a condom but he took it off stuck it in 1 time pulled out and came on my butt.

My ovulation should have been 4 days later, according to the app, if the nuvaring didn't work.

I took the Ella pill 2 hours later. But, I didn't know I was supposed to take the nuvaring out.

What are the chances of pregnancy?? I keep getting very dizzy.
