Pregnancy symptoms

Yes! I’m finally pregnant again! Baby #2 due March 3rd 2019. Just an overly worried mama here and I don’t feel pregnant. I barely have discharge and I dont feel sick whatsoever. It’s just different because my first I was puking every day all day my whole pregnancy. I know every time is different I’m just a worry wart. And I stressed really bad over the weekend. I thought I was stressing so bad I would lose this child for sure. But I took another test because I’m crazy and it showed positive. Any advice to help keep my head up? I just want this baby to stay and be healthy
