Late or missed period

Mary

Hey guys.. so we have been TTC for a about a year and a half and no luck. I do have a 2 year old son though. We have a lot of stress going on right now but I’ve had a lot of stress my whole life and it’s never affected my period I was irregular before I had my son but now I am not I keep track with glow and it’s about dead on when I start every month. I was wondering how much stress can affect ur period. We never tried this month so there’s no way I could be pregnant but I’m on what’s supposed to be my last day of my period and I never started. ... any thoughts?
