Extreme anxiety :(

Ashley • Avoiding pregnancy. 3 losses (6, 16, 15 weeks). 1 earth son, Lincoln born at 26 weeks. Just turned TWO & doing great!
I just needed a place to vent and get support. I have my 12 week ultrasound on Wednesday, I am so paranoid I will go in and have no fetal growth & no heartbeat. I have had 3 ultrasounds so far and no problems but my last pregnancy I went to my 16 week appt and the baby had died. I almost feel like it's a form of PTSD. I do not know how to calm down
