expecting mother

i just found out i’m pregnant and i’m only 19, i’m not very close with any of my family besides my mom. of course she’s helping as much as possible but she’s also completely in shock, so, from an outsider mother in, what was your do’s and don’ts? sickness help? (haven’t had any yet, hopefully don’t but still!) what vitamins did you take? any tips or things i should know that doctors don’t mention? must haves for when baby gets here? any tips will be well appreciated! thank you ladies!
