Is this baby??

Anne
So I have an anterior placenta and planned on not being able to feel our sweet little girl for awhile. Im 20 wks 3 days right now. But as I'm laying in bed tonight (on my back) I swear this is her moving..but I can't explain it so bear with my as I try! It's about 2 inches below my belly button. At first it was like a...rub? Across the inside. And I've been sitting still and keep feeling *shifts* in the same spot. What are the odds this is baby??? I'm almost in tears from excitement because I think it is. (It just doesn't feel like what other people have described it like)
