Hi Bok,
is the pain there all the time, or is it mainly after you eat dinner,,,,does it hurt to breath when it happens, and make you feel sick??
The reason i ask, is that is sounds like the pain i got when my gallstones were acting up whilst pregnant. It got so severe after I had DS3, I had to have my gallbladder removed.

Apart form that, I agree with Alan, those hormones can do some pretty amazing things to our bodies, and we do tend to get funny aches and pains all over at times. If you are at all worried, dont hesitate to see your doctor, or midwife hun, i hope it eases soon for you.
Oh, Emma, One of the things my last DS loved to do, was wegdge his foot under my boob when i was sitting down, and then kick it, making my boob jump up and down. Quite embaressing when u are waiting at the antenatal clinic with like about 20 other mums hehe
