Ovary pain

Hi there. The last 18ish hours I've been expiriencing really sharp pains in my left lower abdomen about where I think my left ovary is. I'm not running a fever and I've been off my period for a week. My mom thinks it's just an ovarian cyst which isn't severe but the pain has been going on longer than what i assume it would be for that. I think I'm going to go to the doctor today but I am scared and just don't know what's going on
