Conceiving after depo

I have been TTC for nearly a year now and no luck. I'm slowly losing hope that I will be able to have another baby. I got another BFN today. I'm 21 and my husband and I are trying for our 2nd. Getting depo was probably one of the worst decisions I've made, I feel like it has totally messed me up. Can anybody give any good news, outcomes, etc for a situation like this? I need reassurance and to know I'm not alone. This is so hard.
