Is pain when having a bowel movement after a tummy tuck a cause for concern?

I had my bowel movement for the first time 7 days after my tummy tuck but it was very little so I still felt very constipated, so two days later on day number 9 I went again and this time it hurt it a lot when I had to push and I felt like something move inside my tummy, I called the doctor and she told me if everything look the same it was because probably everything was okay but I'm still very worried and I want to ask if somebody went through something similar thank you
