FTM ? About weight gain/loss

I'm not sure if I read it in Glow or on what to expect when you're expecting, it it said that while you steadily gain through pregnancy towards your last few weeks you lose weight. Not a lot, but maybe a few pounds. Has anyone who's had kiddos before, or who have already delivered, did this happen to you? I'm not looking forward to weight loss, it's just that at almost 34 weeks I find myself more tired and wanting to hydrate while having a very low appetite. Thanks in advance!
