Ohhh my poor back! Suggestions?

BritteB

I am 24 weeks today. I am having horrible lower back pain and have for the past week now when I'm on my feet for too long.  I just had a doctors appointment today so there's no need to worry about preterm labor.  I've had the suggestion of pregnancy pool exercise classes but I HATE public pools!  I really just don't have the time for an exercise class anyway.  I work out, like I always have, in the evenings when I'm done with work, at home.  Anyway, has anyone found any other solutions to lower back pain?  Back/belly supports, some type of stretch or muscle building exercise move I can do at home? HELP!
