Implantation cramps?

Joy 👼👼 🌈 👶🏻

What did implantation cramps feel like for you?

I had a chemical pregnancy not long ago and back then when I experienced them they were closer to period cramps but mild.

This time its localized to one side and my lower back. It feels more like a twinge or pulling. Not 100% sure that its implantation but I'm 8 days from my period and I never cramp this early. Curious what others experience...

Thanks!
