Morning Glory is correct, each person is different. Your body will be adjusting to its new change, and has a settling point where you might start to feel better. Most go into surgery being the worst off and the surgery is there to get them back to a new life to get back to a new normal. I had the same surgery and from September to November before I went back to work things were changing and foods I avoided I was slowly able to introduce back into my diet but some things took up to a year before I risked some things.
You know your own body, if you feel something is wrong always consult your doctor or his or her team, they normally have a team including a PA to contact.
