6 week belly

I've read woman telling other women that there is no way they can have a belly bump at 6 weeks. They say it has to be bloat. I had a belly before, but my belly is huge right now. My jeans will not button or zip and my belly is pushing down my XXL yoga pants. This is crazy. I'm not eating much because my stomach feels upset so much. My husband keeps commenting on how big it is already. If my belly keeps this up, I'll have no choice but to start telling everyone because it will be hard to hide. I don't know if this is bloat or not, but it only seems to be getting bigger.
