Anyone feel like this?

Metal
I'm 5 weeks exactly today. This will be my third pregnancy. My oldest is one. And the last baby I lost in December. As of right now I feel like my uterus is tightening? I guess a better way to say it is like when you eat to much and then you attempt to suck know your stomach. I feel majorly bloated and nauseous. Anyone else feel/felt that way?
