Last week I was started on a combination birth control pill to stop bleeding that has been ongoing since my IUD was placed in December. So the 1st day I was told to take 4 pills then 2 them 2 then 1. The first day I took the four the next day I took 3 and then I developed gallstones which I never had. I m healthy but just had my 3 rd child he is 5 months. So yes I m a bit overweight but otherwise healthy so I went to a surgeon today for consult on gallbladder removal upon assessment the doc asked if I had thyroid issues and recommended I get an ultrasound in the near future. My question do you think the possible thyroid issue and the extra estrogen could have contributed to the stone formation and that I should correct those things riser before totally removing my gallbladder??
