Scan/eval with high risk ob

Jennifer • Hopelessly in love with my soulmate, mother of four beautiful kiddos: 💕03/03/08, 💙05/06/10, 👼💙09/28/18 - 06/02/2020, 💙03/27/2022 and current expecting #5 in July

My OB who deals with high-risk patients herself, has given me a referral to go to a super high risk doc for a scan and evaluation. The appointment is tomorrow afternoon and I'm a little nervous. Has this happened to anyone else? There is nothing wrong with my pregnancy, just with my own health.
