Query: Nice but I could not use it

This band can provide back support if you are not experiencing any other issues due to pregnancy. My abdominal discomforts, especially sharp round ligament pain got worse with the band. And also, because of the pressure, I felt the urge to run to the restroom every half hour. But of course, if you are having a pain-free very comfy pregnancy, and just looking for back support, this band could be for you.The sizing info is a bit tricky. I am 5'6" and my pre-pregnancy size was 0-2 (occasionally 4) or XS-S. Now that I'm passed midway, I hit 136lbs, I got the size S following the chart. There is no way I could fit into smallest setting. The medium setting provided support while giving more room for the future. I think I would use the largest setting at the end of my pregnancy, but I ended up returning it because of the discomfort I had.
