Worried

Natasha
Hi this will be my second baby but had around 4 miscarriages before this and a miscarriage just before this one now , I'm around 3weeks pregnant but worried as my first pregnancy I went into labour at 26weeks as I had pylonthrilitis (infection in kidneys) he was born at 2lbs 5 and spent 7months in the NICU before he came home. Scared it would happen again .
