Hi and welcome.
This is the time for scar hypertrophy and swelling around the area along with slight tinge can be felt, Nothing much to worry about as far as you have no nausea, vomiting, bowel problem or abdominal pain. You can massage the area with olive oil and abdominal distension is most likely related to premenstrual time. Nothing much to worry about.
Let me know if you have further questions.
