So I missed my period and it's been 3 days so far but the app glow changed when I start my period because I clicked missed my period. Do I just wait it out? I had sex on my ovulation day with a 33% chance of getting pregnant according to glow. My husband and I have sex every other day and every day on the weekends. We use pre seed and I also take prenatal, I've always kept track of my ovulation days. Any advice?
