Extreme bloating

I'm 6 weeks 3 days and the last week my bloating has been so bad. When I get up in the morning it already looks like I'm 5 months pregnant, when I eat something it looks like I'm 6 months. it's making it very hard to hide my pregnancy. I'm scared people will notice at work. Usually I always wear high waisted jeans with tucked in t-shirt but can't wear that at all. Anyone else having this problem? (Alsof very tired, even after a 12hour sleep at night, constipated and nauseated)
