What are your experiences with Implantation Cramping?

Hi there!

I'm currently 10/11dpo, and have been having mild cramping since this morning. Originally I thought it was pre-menstrual cramping but as the day goes on I'm noticing that they feel a little different than normal. Usually I tend to feel my period cramps more in my lower back/left side, these are very forward in my pelvis and they feel central. I'm feeling them in the area right below my belly button/above public line. I have no spotting yet, but I'm wondering if these could be implantation cramps?

I'm curious as to what you all have experienced as far as implantation cramps/bleeding and how early or late in your cycle you felt them and went on to have a BFP?

Did they feel different for you than normal pre-menstrual cramps?
