TTC @39

I've been TTC For 8 months this month I'm 39 (40 in July )my partner is 37 looking for a cycle buddy I'm praying this is our year . I've been so discouraged we hit our ovulation days when we can due to his work schedule. I'm currently on geritol and preseed. I know my age is a factor . 
Has anyone gotten pregnant at 40 also I've been off by a year next month ( Nexplanon for over 6 years)
