I know it's hard not to worry, but try to relax - that will help!!!
My family (my husband, three kids, and myself) takes a liquid, whole-food nutritional supplement called Body Balance. All ingredients derive from things we are supposed to get in our diet, but rarely do because our soil is so depleted of nutrients now. We love this product and I'm very impressed with the company and it's other products as well! I am pregnant with our 4th and have taken this throughout my pregnancy (I showed it to my OB and she saw nothing wrong with taking it). I have heard stories from other customers (with varying ailments from HBP, diabetes, fibromyalgia, lack of energy, hard time sleeping, asthma, etc.) about the wonderful things this product has done to bring back their health and wellness (many times eliminating the need for prescription meds)!
If you're interested in finding out about the product, go to www.mylifeforce.net/catiemadden. The site has a product list and description (you could print it out and bring to your doc to take a look at), testimonials from MANY customers, endorsements from health care professionals (over 160,000 docs, nurses and other HCPs endorse it), and background on the company itself (it's over 28 yrs old, internationally known, has an A+ rating from the BBB, is debt-free and owns it's own manufacturing company which eliminates the middle-man).
Good luck, J., and congratulations on your pregnancy!!!
