Advice

Okay guys as y'all know I thought I was pregnant my period was 2 days late and I got my period this morning :( I was hoping to get pregnant. I have been off debo for 2 and half years and although before I was trying I want to start trying now. Any suggestions on how I can get pregnant? Each time I thought I was pregnant it came out negative and I got my period. I don't want to loose faith or hope but I'm starting to become sad. Any advice or remedies? My gynecologist told me my ovaries and uterus is good when she does m exams and my husband is good he has kid already so I know it's not him. What should I do to start trying?
