Red gum in the implant area

I got dental implant for my front tooth 3.5 month ago and gum around implant area is still red. In the begging of my treatment doc told me it will eventually turn to normal pink clr but it didn't. Also after last time my doctor removed temp tooth for check little bit of pus started coming out from under my gum. Since I noticed it I visited my doc 2 times he gave me ointment , did XRay and assured me that everything if fine. But after 2 weeks little bit of pus keep coming out . What should I do ?
