<s>[INST] 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 [/INST] 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 don't 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.  </s>
