Almost 20 week appt.

Well I went in today and they checked my cervix, since I continue to have light spotting and continued contractions. The doctor said the exterior of my cervix is open but the internally the part closest to the baby is still closed, so that is good. I need to continue to stay off my feet as much as possible and no sex. The baby is low. His/Her feet are on my cervix.  My blood pressure was great 112/80. I go back in two weeks for a cervix check and then in three for an u/s and a cervical length check.  I need to up my b12 and start iron. I do not have absorption issues but I need an iron that is not going to sit above my band to long. What does everyone else take brand wise?
Anyways, thanks for listen to me ramble and all of your support. 

I have brand new sealed chewable iron tablets from bariatric advantage if you'd like them. They are 29 mg of iron, 60 mg of vitamin C, and 10 mg of fructooligosaccharides (FOS). I have no idea what the last thing is, I've never heard of it. I know that it came with my chewable multivitamin I ordered through them and I don't need the extra iron so I never opened it. The expiration date is Feb 2011. Let me know.
