Sharp pelvic pain

Sharp pelvic pain every now and then. My period isn't due for another 7 days. My breasts have been hurting me so bad which never happens until day before period starts. Anyone ever experience sharp pelvic pain? It comes and goes and never lasts for more than a few seconds. What could this be? Doesn't feel like my normal cramps that are telling me my period is coming. Feels different. Anyone ever experience something like this?
