Did you get hyperemesis gravidarum in your second pregnancy but not in your first?

So my husband and I have a 10 month old son and we want to try for a second child this summer. At the very beginning of my first pregnancy, I had high hopes that I wouldn’t suffer from morning sickness. Neither my mom, nor my sister had it and I thought “Yes, so most likely I won’t have it either.”. Well, I was wrong. I had nausea from week 6 - 12, the entire day. I didn’t vomit though (I have emetophobia. The last time I vomited was last year in August, but it wasn’t as worse as I thought.)

I took some meds like Nausema or Nux Vomica which eased it for a few hours. My breakfast was basically only one rice waffle before getting out of bed. I could only eat pasta, pizza or seafood as I was disgusted by meat. I actually knew I was pregnant when I ate shrimps in a restaurant which never happened before. I also craved sushi (which I also never ate before) and salad throughout the entire pregnancy but I wasn’t allowed to because of toxoplasmosis.

I won’t have a problem with the same nausea I had the first time. It was manageable but still annoying. I’m so afraid that I will get HG in my second pregnancy.
