Sadness about going into labor soon?

I'm 39 weeks and being induced tomorrow due to having Factor V Leiden. I had to take blood thinners my entire pregnancy to prevent miscarriage and stillbirth and inducing helps us time it so I can get off them in time so I don't bleed to death. I'm so excited to meet my baby, especially after two previous miscarriages. But for some reason I feel sad. I'm scared of something going wrong. I'm afraid of never seeing everyone again. And I feel guilty because don't most women feel impatient and excited to reach this day? I'm terrified and so sad. Is this normal?
