Implantation cramps?

I’m 7 dpo and getting extremely faint positives and was wondering if anyone has ever noticed implantation cramping? Yesterday i had cramping throughout the second half of my shift at work, felt it mostly on the left side, felt like a pinching pressure. There were intense pain moments similar to period cramps and it seemed like i felt it near my rectum too (could be related to my slight constipation I suppose?!) 😳
