First wiggles?

I might have felt the baby's first movements this week! Once on Tuesday and once last night. It is hard to say though because they were over so quickly. It kind of felt like someone running their finger across my stomache, but from the inside. I don't know, it might be some new kind of indigestion. Maybe if it keeps happening I will be able to figure it out, but now when I try and feel movement all I get is my heart beat in my tummy, not nearly as exciting.
