NuvaRing

I'm about to start the NuvaRing next week and I'm just kind of nervous about it. 
Like I'm scared it will fall out while I'm peeing or something and I won't notice, hopefully that's not the case though! 
I guess what I'm really freaking out about is will my partner feel it during sex, whether he's fingering me or inserting his penis? (Kind of my biggest fear right now)
