Implantation cramp??

Hi ladies! So I’m 11 DPO and tonight I’ve got these strange, pulling-feeling cramps in my center (kind of lower) abdomen. Feels like a tight, string like cramp. Literally never experienced this before! Anyone have anything like this when they noticed implantation, if so, or before their BFP?? Took an early detection this am and it was still negative but AF is due on the 6th....

This is so weird y’all. I’m trying not to sike myself up however I’m experiencing new things and def not like usual PMS...

Curious to hear your thoughts! Wish me luck!!🙏🏻💕
