Why am i convinced something will happen to the baby???

I am 4 weeks 2 days (11dpo) and i’m so so worried/convinced something will happen to the baby. I’m still in shock and it’s hard for me to picture that I’m having a baby right now but i’m very happy about it. My HCG level at 10dpo was 51.57 and progesterone was 19. I’m currently on a progesterone supplement. How do i get through this first trimester without driving myself crazy or at least to the first appointment??
