I Have A Question About My Nuva Ring. I Always

I have a question about my nuva ring. I always check after intercourse to make sure it's still positioned right. This time it did not come out during intercourse and when I went to see if it was positioned, b/c I was feeling some discomfort, it wasn't there. I've reached as far as I can and cannot seem to feel it. It didn't come out during intercourse b/c I checked my boyfriend and the place where were having intercourse and found no nuva ring. Is it possible that it was pushed to far for my finger to reach during intercourse and if so what should I do?
