Depression

I been trying to conceive, for almost a year now. I havnt had any luck. Everyone i know is pregnant or just had a baby. Im starting to get wicked depressed. I feel like im doing something wrong. I take ovulation test and track periods and take prenatals. My husband doesn't say anything about it just"maybe next month" i dont know how he feel at all. I get so emotional about it i never bring it up. I feel so ashamed to tell him my period has come evey month. I just wanna give up, maybe god doesnt want me to have children. Need positive advice/hope...
