Postop Appendectomy

I just recently had an appendectomy a couple weeks ago via open surgery. He started laporascopic with a cam but Was full of fluid so he went to open. He removed the appendix, cleared the fluid build up, noticed I had adhesions in my small intestines, and a couple cysts on my ovaries.
After removal of the appendix the pain is gone and I feel back to normal. However, it has been a couple weeks and my upper abdoman and the general area is starting to have a dull pain. I have another appointment check up in a week. Is it just recovery related or are there some post op complications that would include dull abdominal pain.
