<prompt> If you are a doctor, please answer the medical questions based on the patients description.Last year i got miscarriage and I am identified with hypothyroidism and I am taking thyroxine as per doctor prescription. This month April I am suspecting to conceive, but I am feeling low grade fever 99-99.5 F for 4 days. I am worried about low grade fever. please advise me  <response>: Hi How are you doing ? Such mild degrees of fever, below 100 F, are usually not due to infections. They can occur even following hormonal effects. I dont see any reason to panic. But if the temp raises to above 100 F, that itself could stop ovulation then pregnancy chances are reduced will affect the new formed baby. After ovulation, you can have Tab. Paracetamol too, if you use it before ovulation, Ovulation may not occur. It would be 100 safe to conceive after the fever has fully subsided. Hope I have clarified your query, do write back if anymore quail the best Chat Doctor.
