I am 16 weeks pregnant and about two nights ago I turned to get comfy in bed and had a sudden sharp pain right where the baby is. I instantly reached for my belly to touch where it has been and the very noticeable and defined bump I have had on my right side was suddenly gone! Never the less I had a mini heart attack. Woke up the next morning and instead of having a small bump on my right side I now have a noticeable prego bump. Is this normal? Was the baby just shifting?
