I'm 31 wks. Over the last few days, I've noticed a big change in how baby's kicks & movements feel. It can be so very very painful that it makes me jump and scream in agony. The pain only lasts for a split-second or so, and generally comes at exactly the same time as I feel a movement. It is not this painful with every movement, the bad ones just come sometimes and hit me suddenly. It feels as though baby is hitting on a nerve or something and maybe this is what is causing the pain. Last night there were about 10 of these in the space of about half an hour, which is the worst it's been. Has anyone else experienced this? Is it normal?
