Hi, Gestofit 200 mg contains progesterone only that is used in the treatment of various types of menstrual and pregnancy related problems which are usually resulted from hormonal disturbances. It helps the uterus to become prepared for pregnancy by thickening its lining and this condition is very much important for a successful pregnancy. As Gestofit is mini pill, as it contains progesterone only, so it is considered to be safe during pregnancy according to the various evidence based studies, gynecologist s advice etc. So, it may not cause any harmful effects on baby s overall developmental progress and growth. But, some studies have also suggested that it may cause harm on baby. So, you should consult your doctor first. Your doctor will suggest to take Gestofit if considered essential after assessing the overall merits over demerits. You should take this medication in dosage and duration as advised by your doctor. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Zubayer Alam, General And Family Physician
