Ovary pain

Virginia • Mother of 4 with our last little guy being born at 26 weeks. All is well and everyone is healthy. We are blessed 😇
I'm on my period, cycle day 3 to be exact and since last night I kept feeling sharp pains where my right ovary is. The pain was off and on and not consistent but it was sharp. I woke up this morning and it's still there lightly, but not as bad.  Wth is that?  Anyone ever have that?
