<s>[INST] Hi, I am 5weeks 4 days pregnant and got cold with light fever 37-37,6C. Now I am very concerned if this higher temperature can cause some damage to the embryo since now is a critical period for neural tube closure. I m taking folic acid regularly. Do you think this can damage somehow? [/INST] Hello dear, I understand your concern. In my opinion the pregnancy is a low immunity status where the infections are common.Don't worry the cold is a common viral infection. And the temperature which you have is just mild and does not lead to any complications like miscarriage. So relax. Take medicines to decrease cold and Paradox. Avoid chill items and take adequate fluids up to 3 liters per day. Nothing to worry. If infection develops the antibiotics might be needed. Avoid stress. Continue prenatal like folic acid. Hope this helps. Best regards... </s>
