According to the app, today is my ovulation day. However, I've been having twinges of pain in my lower right abdomen. Nothing too painful and doesn't last long but it is consistent. Anybody know what it could possibly mean?

My CM is a milky water consistancy. Never had a white but watery CM fluid. If it's been white it is normally creamy and if watery, it is usually clear.

Note: my cycles are irregular due to me having PCOS. Therefore, I really cant go by the dates predicted on the app.

Also, another app I use states that I ovulated last week. So I really dont know.
