Implantation bleeding

Heather

So I think I might have had a vvvvvvfl this morning. I've had very small amounts of spotting today. Only when I wipe and only like twice. Not a lot. If I wasn't paying attention I probably could have missed it. Anyone experience implantation bleeding? I didn't experience with my first. Anyone have it with one baby and not the other or should I prepare myself for AF?
