By the way, I don't take or sell the stuff myself but from what I've read about it, I wouldn't worry about taking it if pregnant, if anything it will benefit your fertility and pregnancy as it is apparently "vital nutrients." I definitely think it's a good idea. And it's so expensive, it's not like you're gonna overdose! People practically count the stuff out by the granule!
For your abdominal fat, you might want to head over to the Castor Oil forum, try a series of castor oil packs. And bowel cleansing, if you haven't done that already.
