Typhoid fever. I should worry about?.

More than 14 days have been passed.. But still I am suffering from low grade fever that increases above 99-99.8 in afternoon and becomes normal at midnight.. It specially increases when I do even slight work..this mild fever increases with slight headache.and.i am having a lot of gas. . Initially when fever came I had body pain and headache at one side.. Then a week later I checked for blood test.. Where widal test got positive with s typhi O 1:160 and s typhi h 1:80.. S paratyphi ah & by nil.. But in typhidot test salmonella typhi igg & igm came negative.. So is this really typhoid or something else I should worry about??.. I have been treated with cefixine 200 dolo650 and nexpro rd40 for 8-9 days.. If it's typhoid how much time it will take to go away this low grade fever.. Please.. I am little worried about it..
