I occasionally have this but I also had a hernia repair 5 years ago and attribute it to that and my belly stretching. I usually put a warm wash cloth on my belly when it really bothers me and it seems to help.
Its stretching..The navel skin is sensitive and thin..I had this really bad in my early 20 weeks and it would hurt so bad to bend, laugh, cough, anything really and felt like LO was trying to pull my belly button out from the inside .. It still gets sore but its not as bad as when my belly was going through the growth spurts..
