Ovulation

I work shifts that include days and nights. I mainly work day shifts but my week to work nights always falls on my ovulation period. I have noticed this over the last few months. Even If I was on clomid or anything like that i would be on nights when I should be BD. I havent spoken to my manager about this (she iss off work for a few weeks) I have a good relationship with my manager but i didnt want to delve into my ovulation schehdule with her. I also dont see my husband when on nights due to the work we do.
