Pelvic/lower abdominal pain

Has anyone had alot of pain in the pelvic/lower abdominal? Sometimes even shooting into what feeling like my actual crotch.. sometimes it's sharp, other times cramps but not bad enough to feel like menstrual cramps. No bleeding but it is starting to worry me a little. Had this off and on since 8wks, but it's pretty much constant now at 13wks 4days?..
