Twin moms I gotta question

Annie

Do you remember feeling implantation pain? With my first I felt it and it was like a sudden stitching/pinching in one spot on and off and ultrasound confirmed the area. This time I felt it on the left of my uterus and a couple days later got the same pain but a spot on the right. So now it's been over a week and I'm still feeling this in the 2 spots just like I did with my son but more intense now because it's accompanied with a stretching/pulling sensation. Did you have a similar experience or maybe this is just my body reacting different the 2nd time around?
