Michelle, unless your surgeon gave you instructions otherwise, you stop using walking aids when your body signals that it's ready. Those signals could be:
1. You get up and walk a little ways and suddenly realize that you forgot to use your walker/cane/crutch/whatever. And you did just fine. Did it hurt? No. Did you limp? No. Now you spend a day or two doing short distances in your house unaided. Then you try a bit longer distance outside. Keep the aid close by in case, but you gradually increase your distances and see how it goes.
2. You consciously try a short distance in the house unaided, and it feels fine. Same as #1.
The goal is to walk with a normal gait. If you still limp, then you still need your walking aid a bit longer. If you have pain, that tends to cause the limp, so you still need your walking aid a bit longer. Also, as you go further away from home, keep in mind that fatigue can set in quite abruptly. You don't want to be a quarter of a mile from home and have to limp all the way back in pain. So start small (like your 3-4 steps) and lengthen that a little bit each day.
And for anyone else reading this and comparing.....please don't compare! There are many variables involved in when you give up walking aids. Some of us do it in a month or less. Some of us take several months. For some... it can be even longer. There is no "normal." There is only YOUR normal.
