TTC for over a year

Hello ladies! So ive been trying to conceive over a year now. I have a 3 gonna be 4 year old daughter. I was on depo for a year after having her then I came off of it. About a year later when I finally got my period back after not having it for the year after coming off of it, we decided to start trying. I feel like depo made me infertile 😭😭😭 any tips or advice?
