TTC for 1 year - sad - Nuva ring

Ashley • Soon to be momma.
I'm 31 and have been with husband for three years now. This December will mark my first year trying to get pregnant. No BC or anything else and plenty of trying. 
I'm really having a hard time even still thinking that my husband and I will be blessed with kiddos and I'm getting really depressed over it all because it feels like I'm messing it up. 
​I was on the Nuva ring before but I've been off for about a year and a half now. Didn't know if anyone had any thoughts or suggestions... I'm getting worn down here.
