Nuvaring help

I had my first nuvaring in Jan they expired in January but I put my second one in last week(it wasn’t expired) and I had sex the night before and he did finish inside me but the new one had been in for 9 days so I should be protected from pregnancy right?So I had sex around 2 am and I just thought about my birth control so I checked to see if it was still in and it wasn’t so I just put a new one in he didn’t cum inside me so I’m not worried about the pregnancy part. I put the ring in on February 26 and today is day 11 so would I still take it out on the 19th or would Saturday’s be my new ring days?
