Pregnancy fears

*WARNING SENSITIVE TOPICS AHEAD*

Just found out I’m pregnant with my first. Very early at 4w3d. I have my first ultrasound on June 7th, which is killing me that is so far away. I have not been able to stop my mind about the fear of miscarrying. I’m so terrified about every little thing. My mother has a history of miscarrying, idk if that has any correlation. I am generally pretty healthy. I don’t take any medications. Pretty active. But with a stressful job (ICU NURSE). If anyone has any advice or kind words I would love to hear some. If you don’t have anything nice to say, please move along. Thank you.
