My period is very irregular, and my cycle can span from 16 days to 32 days; however, I'm due a period sometime between late last week and this week according to Glow. It's hard to tell if I've already missed my period for the month due to my aforementioned irregular cycle -- I'll be trying a pregnancy test tomorrow morning but I'm not entirely sure if that may yield a false result due to early testing, as my period may not be for another few days. I've also been under a lot of stress lately, so perhaps that is the cause of a possible missed period?
