Worried..

So today I decided to take a test. As of today my period was 6days late, my periods are usually pretty irregular so I didn’t think much of it but I stopped at the store

and something just told me to grab a test. So I did and came home to take it.. I’m in complete shock but also very very happy. Last November I was diagnosed with an ectopic pregnancy my doctor had told me to just wait it out that the baby would expel on its own.. well not even a couple weeks later I was rushed to the hospital because my tube started to rupture. I lost my baby December 21st 2018. I had to have emergency surgery and recovered in the hospital for 2 days. I’m so scared that this will happen again or that I will miscarry. Is there any way to help myself from feeing like this? I don’t want to stress about it to much I know it can effect the baby but it’s just so hard when I went through such a traumatic even not even a year ago. Do any of you ladies have any advice or has this happened to anyone else.? I’m still in shock but anything helps at the moment.
