Banded 6/13

I got banded on 6/13. I feel like I had a tough recovery. A lot of discomfort. Then gushing and swooshing sounds through my stomach. Then liquid stools. Then got my period which I hadn't had since November. I am 5 days out and still uncomfortable. Only drinking clear liquids and protein shakes. Sometimes I feel like I need more calories because i get lightheaded and shaky. I get a gas pain up and down my esophagus after drinking something. Then I can't seem to finish my water or protein shakes towards the end of the day because I am too full. Is it normal to feel what I think is my port site on right sife of my belly? Feels similar to when I was pregnant and the baby's heel was pushing against my stomach. After 2 c-sections and gyn lap surgery, this is definitely a harder recoery than I had envisioned.
