I'm pretty sure I felt the baby move this weekend! It felt like little butterfly wings tickling me from the inside. It happened several times, and always in the same spot.
I was miserably sick and stayed in bed reading the whole weekend. But anytime I laid on my right side, I would feel a faint tickle under my ribs on the left - just where the doc said the baby was sitting. The baby is about 5 inches long and weighs 4 oz at this point, and according to the books I should be able to feel movement anywhere from 13 to 20 weeks.
This is getting exciting!
