TTC number 2 with 85% chance of suffering again... 😥😥😥

I suffer from HG when I am pregnant. Only 2% of pregnant women suffer from HG! Just wanting to know how many people have had HG and if you have any advice. My first pregnancy was horrible. My doctor literally thought I was going to die. My husband and I are trying for another baby and if anyone has any advice that would be great. My son is 3 now! I tried EVERYTHING with my first pregnancy. I have an 85% chance of suffering if I get pregnant again so I would like to be prepared! Thanks.
