Thanks for posting your query. Sorry to hear that your last pregnancy ended in a still birth. Congratulations with your present pregnancy. As you have had a full work up done to find out the reason of still birth and it was due to anemia, it makes sense to treat it. Please continue folic acid (foliage). OB Mom and Micron C are multivitamin supplements, you can take one of them. You have not mentioned whether any tests were done on baby after still birth, as that information may be useful. Duvadilan (Isoxsuprine) is a medicine that was used to prevent preterm labour. Its no longer first line drug for prevention of preterm labour. I am not sure why it has been prescribed in your case. Please get back to me with the missing details so that I can give better advice. Hope this help. All the best, take care.
