Lightning crotch ? 12dpo

Aja

Okay so last night i had intense period like cramps and then i felt like cramping my lady parts. Like off and on pain i only felt when i was about to give birth to my twins ( they are about to be 3 ). Im super confused. I dont get cramps before my period only the day it starts. No bleeding. The cramps have mellowed down some but i still have that crampy feeling in vag and it goes to my butt too. Sorry tmi. Anybody get this ? Im 12dpo.
