GB attacks during pregnancy?

Hi:
when I was pregnant 3 years ago, I used to get shooting pains on my right side of the abdomen. I thought it was due to my increase in the size of my uterus that it is pushing other organs.
Those pains simply went away, after the delivery of my daughter ( July 2003). And have never happened. But I have been plagued with digestive issues like bloating/constipation.

I was just wondering, could those pains be coming from gall-bladder.
I have had an ultrosound Jan 2006, it came out normal.

Anyone experienced GB attacks only during pregnancy, which went away after the delivery?

Please respond.
