Right or left ovary pain before period, should I be concerned ?

I’m having new right or left ovary pain 3 days before my period. I didn’t used to have this but it’s been going on for the last couple of months. And I’m TTC so I’m worried it could be apart of why it hasn’t happened yet. I wasn’t sure if it was a health concern or is it normal? It’s like sharp pain and it lasts for a day on and off.
