M.,
I had the same thing happen and while one of the doctors in my group was worried and had my husband and I a total wreck, my regular ob/gyn told me he was just going to watch it. In my case it did move, but had it not they were going to schedule a c-section before I went into labor. From what I have learned in nursing school it can be extremely serious if you go into labor, but with modern technology they can see it before hand (usually). If you are really concerned I can give you the name of my doctor whom I have been with for 22 years and trust him beyond trust; the guy is brilliant with one heck of a bedside manor. My last two kids would not be here if it wasn't for him.
