4 months pregnant. Less appetite, bloated..

Lynn
Until last week i ate like a horse and was always hungry. Now 4 months this week, finally starting to show a teeny weeny bump but totally bloated in the evening, I'm finding my appetite isn't as big as before. I get full quickly and feel so uncomfortably bloated. It goes down by morning. Anyone else have this? Now i am eating everytime i do feel peckish as baby needs food more than i do. Evenings are definitely the worse time though for not feeling like eating as i feel too bloated.. is this normal? :-(
