Iam sorry for your condition. In my opinion there are various reasons for miscarriage like:-1Genetic anomalies.2Infections like Malaria, TORCH infection, CMV etc.3Hormonal abnormalities like thyroid abnormalities, diabetes,progesterone insufficiency etc.4Uterine abnormalities. So the fever can also be the cause for miscarriage. But the cause of fever should be found. And thyroid if it is under control does not lead to complications like miscarriage. Evaluation for TORCH and CMV might be helpful.Dont worry. Once the cause is treated it might not get repeated in further pregnancy. Relax. I suggest you to plan the next pregnancy after a gap of 3 months. Start taking folic acid supplements from one month before planning the pregnancy. Nothing to worry. Hope this helps. Best regards...
