Postpartum

I am now 4 months PP. and since about a month after I gave birth I have been having excessive bloating to where it hurts. And everytime I eat or drink anything I get instantly bloated and crampy. Is this a postpartum related issue or something else? Anyone else experience this and what was it? Not on any birth control anymore. I was on the iud but had a lot of side affects and got it taken out. and not doing anything differently diet wise. I’m also always wanting to eat, feeling constantly starving. Not breast feeding.
