I hear ya sister! That's a super healthy diet - and full fat milk per glass only has about an extra 50cal in it (equiv 5 minutes excercise) so no, that's not making squat of a difference to you. I put on close to 20kg with both of mine which is amazing considering I vomited up so much of what I ate and barely ate anything much at all due to heartburn later on. It's the frickin hormones - same thing happens to me with most pills. No stretch marks here either, in fact I just looked like I was getting fatter until I was about 6-7 months as by that time I'd be a size 14, unfortunately it doesn't fall off me though. Have been practically starving myself and still have 5kg to go, seemed to come off very fast after I finished BF DD1 but am still BF DD2 so wonder if those hormones can play crappy tricks with your body as well? Would have loved to have been one of those people who are lighter after they pop the baby out then before, damn it.
