I felt ready well before 6 weeks, but I suppose it depends on what kind of exercise you do. Regardless, I waited because I had no time lol
I will say that within the first week I was feeling great but I overdid myself with vacuuming and other household chores. Everybody is different, so maybe just listen to your body and if you feel more sore, just hang out on the couch or in bed and give yourself time to heal.
