My girlfriend has been using the Nuvaring for 16 days now and we had removed the Nuvaring and had sex today. We fell asleep and realised that we forgot to insert the Nuvaring! It must have been out for 3-4 hours.
We inserted it immediately then.
We have been having sex the past few days and I have always pulled out.
What is the likelihood of pregnancy?
Any help is welcome!
