Weight gain

Did anyone gain more than 10kg in pregnancy? I’m currently 35 week and I’ve gain over 20.. I don’t like like it however I’ve realized my body has a lot of water retention. So far my check up has been okay and I don’t have diabetics and pre clampsia. I heard some people saying gaining above 10 will be hard to lose but I know different body carries differently In pregnancy. I had a friend who gained 30kg but dropped everything after. My mom had the same.
