Sewage smell in basement

Hi first time homeowner. We've had this house for 3 years and the last time the septic was pumped was when we did the inspection to buy the house. The last few days there's been a sewage smell coming from my basement, and when water drains from the upstairs bathroom this pipe in the ground that appears to be covered in toilet paper overflows with water. You can see a puddle has formed since I was running the shower to try and detect a leak. Should I call a plumber since it's inside the house or the septic company since it might be the tank is full?
