Nervous but excited?

Is anyone really really excited to have a baby but the actual thought of being pregnant is nerve wracking almost to the point where you doubt yourself? I’ve had two pregnancies before, one ended in miscarriage and the other my parents forced me to get rid of (long story, very traumatic experience) and I was told it would be difficult for me to get pregnant. This morning I took a test and thought I saw a very faint line and my heart sank rather than skipped a beat. My husband and I are wanting a baby, but we’re like “if it happens it happens, it’s God’s will” but I’m really nervous even though I’m excited? Is this normal?
