TTC on Night Shift

Brittney • Graphic designer turned CNA trying for baby #1.

Been working nights for the past month or so. Read somewhere that night shift can affect fertility and conception. My period is 12 days late and it's never this late. Tested five days ago and it was negative. Have an appointment with the gyn today to see what's going on. Is there any truth to the infertility/night shift connection? Anyone out there get pregnant on night shift? Any feedback appreciated.
