pain in my right ovary and how to tell my mom

Sometimes, it feels like there's a lot of pressure on my right ovary and it hurts. This would happen irregularly throughout the month and not just when I'm on my period. It has been doing this for a few months now and I'm kind of concerned, but I don't know how to tell my mom. We're not close with anything like this. Part of me is thinking that she wouldn't take this seriously. Should I be worried about my body and how could I tell her if it's worth telling?
