I was pretty lucky; I had a very healthy pregnancy. The only issues I had were in my third trimester because I'm poor. I had vitamin deficiency problems and started getting muscle spasms in my back, but since I was on leave from my employer, I had medical benefits that covered the massage therapy and chiropractic care I needed at that time. The only thing that comes to mind, because I don't have a very complicated case, is vitamins; maybe consider including prenatal vitamins.
