This is the 2nd month for my nuva ring I used it correctly the 1st month but the 2nd month I have been taking it out and re-inserting it when I have intercourse. I would like to know if Im protected during intercourse or do I have to use it all the time? I recently had a miscarraige in December and I started the ring in January. I wore the ring correctly the 1st week of my time in February but like i said I have been taking it out and only inserting it before intercourse. What are my chance of becomng pregnant or am I protected while its in?
