Not much I guess. I was so gassy around that time even when the baby is actively moving during the ultrasound, it's still too early. I'm now 17wks and still not sure if the movement is baby or gas. But I will happen soon, I hope :)
If its your first pregnancy you probably won't feel anything til closer to 16-20 weeks. If its a 2nd or more pregnancy maybe around 13-14 weeks you may feel something. Most of the time it is just gas. With my first I didn't feel anything til 22 weeks and with my current I felt her around 17 weeks. Even then it was just a few flutters every now and then.
Its, probably alot, but its still so very small you can't feel it, sometimes that early you could maybe feel like a fluttering but that's probably all
