New to this.

I am a military wife stationed in Hawaii. I have one son but i didn’t find out i was pregnant with him until the day i was giving birth to him. I am now pregnant with my second child and according to glow i am 5 weeks due in Dec. I have no clue what i am doing. I don’t know the do’s and don’ts of being pregnant. Any advice?

Also to mention I am 18 years old turning 19 this month and my son just turned 2. I found out i had a lot of health risk while i was pregnant with him.
