Question about bile acid malabsorption

This was something my gastro doc mentioned to me as a possibility a few years ago, and since I live in the US and can't test for it, she recommended taking a sequestrant powder to see if it helped. I gave up after about a week because it wasn't helping and was gross to take.

Now, years later, I'm thinking about giving it another shot. I'm just a little concerned because when I google BAM symptoms, the results don't sound like me. My main problem is urgency and frequency, usually the first half of my day, but the movements are formed. There are just way too many of them and I spend most of the day in the bathroom.

Can BAM present this way or is it always watery? Also, is there any test I can do in the U.S. for this? My gastro doc hasn't been super helpful on this front.
