sex after birth

Ashlynn • 23. Southern California.
So I had my 6 week pp check up a few days ago. My SO and I waited to have sex since I had an episiotomy. Anyway, at my check up the doctor said everything looked good but I still had a single stitch that hasn't come out yet (apparently it's normal). But she never actually gave the okay to start having sex again...or even using tampons because I'm tired of those oversized pads!! 
Now my question is, should we still wait or should we be fine? I'm in no pain and the bleeding has stopped.
