I'm 11+6 with second baby, and have been feeling slight rolling sensations in my tummy. Almost like I've gone over a bump on a rollercoaster. I did not initially suspect baby, put it down to wind as is often the case. But if I'm honest, it really is nothing like wind. We had a scan yesterday and saw baby moving so much, flipping and stretching and waving arms and legs. I'm now wondering if it actually cld be baby. Has anyone else felt this? It's definitely not flutters, like I remember feeling with ds1 at around 19 weeks. This is a proper rolling sensation.
