What did your implantation feel like?

Amber
What did everyone's implantation cramps feel like? I'm 9dpo and since 7dpo I've been getting a piercing pain in my left side, low down inside my hip bone. Also sometimes I can feel it in my back in the same spot. It just feels really sore! Could it be implantation cramps? Just confused as I fell pregnant in February (lost the bub 3 weeks ago) and the implantation cramps I felt then were like lots of fluttery pinches all over, not like this. Fingers crossed this is my rainbow baby anyway 🤞☺️🌈
