Weight gain and bloating after stopping the pill?

So I stopped the pill about mid-may and now I'm on my 2nd period cycle since then. I know I get crampy and bloated on my period but it was the time on between periods I'm trying to understand. My weight appears to be gaining and I'm still struggling with bloating and I thought women in general tend to feel better and lose some weight after stopping the pill? I was on it for about 20 years straight so I wonder if that's why my body is so angry? Anyone else go through this? Any ideas on a timeline for symptoms to calm down? I do have endometriosis that was removed about 2 years ago. I'm not sure if it comes back and that's acting up? Any suggestions or advice is appreciated!
