So I’m worried that my calendar on my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> is wrong. The first day of my last period was on the 30th of December and it ended on the 4the of January ( so 6 day period) usually my cycle is spot on every 28 days. The usual rule of thumb for ovulation is 14 days after the first day of your period. So if glow was correct I should have ovulated around the 13th or 14th. But glow thinks I’m supposed to ovulate this up coming Sunday. Has anyone else experienced this with the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>? Should I be worried or just go with the flow because I’m doing my best to track everything correctly so I can get pregnant with my first baby?
