HELP IM REALLY WORRIED!

i’ve been on the nuvaring for about 4 cycles now and i’m on my period week and it hasn’t come. i haven’t had any symptoms of my period like cramping or anything but i’m also not having any pregnancy symptoms. my period is usually a few days late, but what’s making me worry is the fact that i’m having no symptoms, usually i’ll have light spotting, cramping, mood swings, and sore breasts. i use the nuvaring and condoms for protection, and even with the condom on my fiancé still pulls out. i’ve never not used a condom and the condom has never broken. i’m just worried and i wanted an opinion of my situation. also, my period week started monday. i don’t understand what’s going on and i’m scared, please help!
