Basically, I imagine it comes down to the kind of wedding you want.
If you had always imagined having the dress of your dreams, a big event, all very perfect and home you imagined it, then you may find it very difficult when things go wrong. So if you don't fit in your dress, don't feel comfortable how you look, know you'd hate it if you leaked over your dress in the middle of your vows, would be upset if you were too tired to talk to everyone, it could be a difficult experience.
If you just want to get married and have a party, and don't really mind what dress you're wearing or if you're still carrying baby weight, whether you spend most of the day sitting down breastfeeding, if you say your vows holding a crying baby, if you don't get to dance or eat much because you are tired or your baby is unsettled, then you will still have a wonderful day regardless.
Because realistically yes, you could still be physically recovering from the birth, hormonal, sleep deprived and with a very unsettled baby. You could have feeding issues which mean you'd rather feed away from the crowd.
Personally I would do it, as presumably your wedding day will be full of family and close friends who you would like to support you anyway and so you will have all the help you need, whether it is to hold the baby or to fetch and carry while you feed all day.
If you're happy to think "I could be an exhausted mess with a screaming baby but it doesn't matter, I'm getting married" then go for it.
Equally, you have every chance of an easy birth or recovery, a chilled baby who feeds happily, and feel great about it all! You just need to imagine how happy you'll be during a sort of worst case scenario birth.
