I used to have pain such as you describe from ovarian cysts. Ovarian cysts aren't routinely of huge concern, and apparently a good percentage of women have them, but the yjust spontaneously pop and resolve themselves. They get a bit more concerned about cysts in more mature ladies - around menopause age, because sometimes they don't burst and resolve, and also they can turn a bit a bit tricky at that time of life.
Have you had an ultrasound scan as yet? That would usually show up cysts in situ.
Please go back and see your Doc again. Dr Google is fantastic, but can also be unhelpful, if we start latching onto something. Stuff like vague, but acute pains could be due to a whole load of stuff.
