Your belly button will pop!
The hormone Relaxin is at play now and will loosen your ligaments (which in your pelvis.. is necessary for the baby to be able to come out), however, ALL your ligaments are affected, some ladies find that their shoe size even increases because of slightly more space between their bones.
Your growing uterus is starting to take over your abdominal cavity, causing heartburn, try drinking before or after meals instead of with them so as not to aggravate the situation.
Your baby is now the size of a...
Coconut (10.9 inches long)!
By now, the baby is hearing some of the world around him, can hear your voice and your heartbeat hears your tummy rumbling and your blood flow whooshing around your body. His brain and senses are developing right now, and he will start to move his hands around and gently start touching his face and will try out sucking his thumb.
He now knows when it's light and when its dark, and you may find that if you lay in a warm bath, with the bathroom lights on.. baby will be alert and moving around.
