Terrified!

I'm extremely terrified of having a miscarriage that I haven't really been able to celebrate the fact that I'm actually pregnant. I'm 7weeks and 5days and This is my 5th pregnancy, but I only have 2 living children. I lost my last pregnancy around this same time last year...and it was really hard on me. I can't get in to see my doctor until June 6th and I'm so scared that I will go in and not hear a heart beat 😕 is anyone else dealing with this overwhelming sense of fear?
