Sharp pelvic pain 5-6 days DPO?

Has anyone ever experienced sharp twinges of pain in your pelvic area that are like little bolts of lightning almost? The first one happened this morning, it radiated down into my vaginal area and only lasted for a few seconds. They've repeated throughout the day, and now I have a low, bloated feeling right above my pubic bone. I usually don't even experience menstrual cramps, so this is odd for me.
