unexplained sharp pain in right lower abdomen?

Anyone ever have a sharp pain in their right lower abdomen? I had a pelvic, transvaginal, abdomen, bladder and kidney ultrasound 2 weeks ago that was normal. I had a colonoscopy 2 years ago that all came back clear.. the only thing that was found was a small ovarian cyst on my right ovary. My doctor has no idea what is causing the pain but I have had if for 8 weeks now 😓. Wondering if anyone else has had a similar experience because I am getting so frustrated not having any answers. I am 15 weeks postpartum and it’s been tough taking care of my son being is such pain!
