Lifting weight after an open appendectomy?

I recently had an appendectomy (5 days ago from the time of me writing this), and i know i'm not supposed to lift 15 or more pounds for the next week and a half, but i have a few questions. I was supposed to have a laparoscopic appendectomy, but they (for whatever reason) ended up doing an open appendectomy. I have a meeting with my doctor at the end of next week, but was hoping to get some possible answers before that. I have hear of peoples recovery times being 2 weeks (laparoscopic) up to 6 months. My situation is that i work at a local furniture store moving furniture that weights hundreds of pounds (me alone or 2 people for large recliners, couches, etc.) and i also am on the high school football team (lineman) and need to do weightlifting in preparation for my senior year next year. How long until i can do both of those activites. The furniture is self explanatory on weight, but also consists of me contorting myself (and possibly my stomach) at different angles in order to twist and adjust furniture through doors and hallways. The weight lifting consists of bench press, squat, clean, and other excersizes ranging in weights from 200 pounds (bench) up to 300-400 pounds (squat) and i know these will put major strain on the stomach. The last thing i can afford to do is get a hernia or other injury from lifting too early. How long should i wait to do these? Also, i dont know if this is any consolation to the question, but for "specs" i am 16, 6'7", and 285 lbs.
