Can anyone relate to this?

I’ve had a few transvaginal ultrasounds over the past couple of months. My last being December 10th. I have right ovary pain, and right lower back pain. Then over this past weekend I had an abdominal CT scan. No cysts or anything seen... I was sure at least a cyst would be there. My period was also 18 days late this month. It’s never ever in my life been that late. It’s always super regular. Maybe 4 days off max. My right lower back pain is so bad right now! And my right ovary aching, very uncomfortable.. I know it’s my right ovary because about a year or so ago I had a complex cyst on that ovary that was very painful, and this pain I’m having is the same, and in the same area. Idk what to think. I’m going into work now - can anyone give me any tips on how to fight the anxiety? Or give me some words of reassurance? I don’t know what to think at this point.
