I'd say the scales were off honey. I've seen your pics on FB and you have not gained any weight on the rest of you (only on your belly where you are supposed to be!) so I would say that the scales were off.

My IL's scales weigh out about 4kg - so I am always 4kg lighter on their scales. Love weighing myself there - here - not so much!!!

So yeah, I don't think you have put on 20kg.

I put on 22kg each pregnancy - and thats because I succumed to junk food for most of them because I was just sooo tired.

This one, I'm actually staying the same for the moment anyway - and usually by this time I have gained about 10kg.

I think I usually put on about 5kg in the last trimester.

You might have a lot of fluid too ya know, and that can weigh a bit.

You know, there is a reason why some OB's dont' weigh their patients (I don't get weighed with mine) cos you don't need to be thinking about that.

Exercise if you can - for you though, not for weight loss - eat in moderation.

*mwah*
