I used to have regular 28-32 day cycles. Then they switched up to anywhere between 33-64 days at the time. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a> through glow says my week should have been this week and ended two days ago. About 30 minutes ago I got out of the shower and noticed that I felt some pressure in my lower belly. Now it's somewhat crampy. Think I could be ovulating now or perhaps an early period which by the way isn't due until June 11th?
