Excessive weight gain?

Did anyone else gain a lot of weight throughout your pregnancy? With my first pregnancy I went from being 135 beforehand to 204 at my 36 week appointment which I ended up going into labor. I did everything “right” whenever I explained to my doctor because I didn’t understand why I was gaining so much weight. I was eating health, 4 small meals a day mixed with healthy snacks, I worked out 5 days a week for 1 to 2 hours a day. I would go on walks with my dogs, I have a two story house so I’d go up and down the stairs at least 10 times a day. But at my last appointment the midwife I saw just looked at me and said “You know you’re obese right?” Like I couldn’t understand why I had gained so much or what was wrong with me. I’m terrified that’s how it’s going to be with my second baby, but all I ever see on here is the cute tiny pregnancy bellies. Did anyone else go through this?

*Edit because I do not wanna come off anon, I did see two different nutritionist that said everything I was doing was right the portions were great as well as the amount of activity I was getting, that they couldn’t explain the weight gain**
