I am 5weeks pregnant now I have fever last weeks it was for 5 days and for two days it was 103degree I am using folic acid tablets from 2months before is there any chances of getting any problem

Having a fever while pregnant is always cause for concern but taking 2mo folic acid pills isn't. Fever is often a sign that you're fighting off an infection and I believe that at this point in your pregnancy there are enough safeguards that the embryo will be safe. It is always smart though to follow up with your doctor. They're going to be monitoring this pregnancy even if it is completely healthy. Good luck!
