My period showed up right on time last month but only lasted 3 days. Then the days that I was suppose to ovulate I got negative ovulation test so it kept pushing my fertile window back and I never got a positive ovulation test but stopped recording the negative ones. And now glow is saying I shouldn’t get my period until November by which I won’t have a period for this month. So should I test when my period was originally suppose to come or when glow says it will come?
