Advice on Smells

I don’t have bad pregnancy symptoms. Everything I’m experiencing is pretty mild but my nausea peaked this week and only comes when we’re cooking something. And bless my husband, he’s been a saint that he’s doing all the cooking now bc I can’t stand the smell of ANY being cooked. Even now, if I’m in my office upstairs with my door closed and I smell dinner, I need to run to the bathroom. Any advice on what I should do to avoid this or how and when this gets better? Lol
