Worried

So I just found out 2 weeks ago I’m pregnant with baby #2. I got supper nausea, hungry all the time, tender breast and tired but now I’m 6 weeks and the nausea and hungry kinda lighten up. Is this normal? I did have a miscarriage back in November. I’ll also wake up depressed. Idk if that is do to my pregnancy or my family issues. Has this happened to anyone and everything turned out fine?
