Ttc 1 year and 9 months

My husband and I have been ttc almost 2 years now, I have done everything from ovulation tests and charting my temp. to taking Fairhaven fertile aid and ovabooster and having my husband take the fertile aid, count booster and motility booster. Nothing has worked. When I started my period last month I decide to give up and quit trying. The only problem is EVERYONE around me is pregnant including my sister and my best friend and neither of them were trying or wanted it. I am so depressed I just want to curl up in a ball and cry all day everyday. So basically is there any tips you all can give me for naturally conceiving that maybe I haven't tried yet.
