kidney/Gall stones

I am 4.5 months pp with my first baby.  I developed kidney and gall stones when I was about 7 months pregnant but they couldn't do anything about it until after delivery. When I was 6w pp I had surgery to blast my kidneys stones. Then at 3months pp I had my gall bladder surgically removed. Needless to say pregnant was not good to me haha! And surgery is tough whith a new baby!!!  But my docs say it's more common in pregnant women to develop these. I'm curious if anyone else has had this problem? And I'm also curious if it will happen again if I ever have another child?
