I am Dr Madhuri a Consultant Obstetrician and Gynecologist and will be helping you with your queries. Folic acid is a vitamin whose deficiency produces brain defects in the baby. Hence it is given to every woman with pregnancy. So please continue it. Osnate is a calcium. It is preferable given after 12 weeks. However some studies suggest that it can prevent development of preeclampsia [ raised blood pressure during pregnancy] when given in the first 12 weeks. This is still debated and I prefer to start it after 12 weeks unless that patient has a history of preeclampsia. Dirogest is progesterone. It is used to prevent abortion. So empirical use will not cause any harm but may not have any benefits too. I prefer to use it when my patients have a history of recurrent abortions or have bleeding or pain during pregnancy. So please discuss about these two drugs with your doctor. If she feels that they are needed, then you may take them. They do not cause any harm to the baby. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have. Dr Madhuri Bagde Consultant Obstetrician and Gynecologist
