Hi I'm 9 weeks pregnant and a few hrs ago I suddenly got severe stabbing pains under my right rib and 6 months prior was diagnosed with gal stones but with plenty of home detoxs and flushes and changing my diet to abit healthier I thought they went away or I flushed them them out. As back then I was adamant about not getting my gallbladder out as its in our body to serve a purpose and do the job the gallbladder is surpose to do, but around 4 or 5pm this afternoon suddenly that pain I once used to get for hrs on end returned under my right rib cage and is still there right now as we speak. I'm thinking of going to the hospital as I'm nearly 39 and this is my 5th baby on the way. Its slowly easing but I'm still unsure what to do.

Gallstones 100%

Gallbladder removal was a cakewalk for me, in hospital 4-5 hours, took one Vicodin that night, fine from then on.
You don't need a gallbladder any more than you need an appendix or a wisdom tooth.
While your diet changes are admirable, especially in that your liver still secretes bile, a necessary part of digestion, and you should keep that good diet, you probably have pain because stones are blocking the outlet. Plan on much more trouble if anything gets infected.

See your doctor for the best options to deal with those gallstones. If they cannot be pulverized and passed, removal is more than likely.
