There is one company that has been supporting bellies for a long long time, since 1987 to be exact. If your doctor recommended back support during pregnancy, it's very likely you've come across Prenatal Cradle. I had the opportunity to review the Mini Cradle and the Best Cradle. These are two great products that are indispensable, especially during the last trimester.
I like the Mini Cradle (pictured below) because even now at 20 weeks I can wear it to relieve sciatic nerve pain in my back/legs. It is great under clothing since it is rather discreet. I have the size small, although petite would probably work better for me (I'm only 100 pounds). The only thing I do not like is that it isn't very adjustable. There are only three settings of hook and loop closures, which can either leave you with something that's too tight or too loose. The same applies to the Best Cradle. For a product that's been around for so long I would expect some improvements for something as fundamental as adjustable fit. Nevertheless, it is one of the best and most affordable available - you just need to try it on to see if it fits.
The Best Cradle (below) provides even more support and is great during the last trimester, especially helpful if you are pregnant with multiples. It is rather easy to put on, don't let the look intimidate you. Though being pregnant through the summer, I have very few shirts that would cover the V-neck straps of the Best Cradle. In the fall and winter it wouldn't be much of a problem.
