6 weeks started the nausea. Vomiting started at 8 weeks and didn’t go away at all until 17 weeks. It was miserable and I lost 10 pounds in the first trimester. I’m 23 weeks now and feeling mostly great!

Never 🤔 unless you count that one time someone reheated some stinky fish

Around week 5. And it's still here at week 9.

Right away. All of my pregnancies I started right before 4 weeks and it kept up all the way to the day I delivered. It was definitely worse between weeks 10 and 14.
