Define 'acute'. It's a very poor description for you to give to someone, as your idea of 'acute' is quite possibly very different to the medical meaning of 'acute'.
Define 'pelvic'. It's a very poor description for you to give to someone, as your idea of 'pelvic' is quite possibly very different to the medical/anatomical meaning of 'pelvic'.
At any rate, with just the pain as a symptom it's very hard to give an idea, but it would trigger me to ask about:
- Where in the 'pelvic' area? One sided, or both? Is anywhere in the region tender to touch/press?
- Any pain on urination or change in colour/frequency of urination?
- Any fever? Any vomiting?
- Any change in your stools or your bowel frequency/any pain?
- Any unprotected* sex, especially with new or casual partners but with anyone?
- Any abnormal discharge?
- Any disturbances to your normal cycle?
- Additional to all of the above, one also always has to ask a lady with tummy pain: could you be pregnant?
