I try not to look too much into things, it just stresses me out. Yesterday (6/7dpo...not sure which) I started to get horrible sharp pains in my sides, below the hip bone and slightly to the side. I also felt like I had hurt my back. It hurt beneath the shoulder blades and around the sides. it felt like I had a stitch, from running etc I felt awful, dizzy and just off. Only last half hour. I then felt fine. Didn't think much of it until I got home and searched on internet. Could this be implantation cramps? Got a small twinge this morning but nothing else. I am not holding out much hope, just curious.
