Afraid to be a mom

Growing up, I honestly never wanted kids. I wanted a nice car and house and to travel and party with my friends. As I got older, I started changing my mind and thinking I wanted that family life.

Well now, here I am. 7 months pregnant, with a SO whom we plan to marry and talking about buying a house and all that. It's crazy!

Now I see all these babies being born and so on and I am so afraid to be a mom. I'm afrad I won't know what to do. But in honesty my biggest fear is that something will be medically wrong. When I was 18 weeks they told me my daughter may have spina bifida and we got sent for an US. Turns out, she doesnt but now I am afraid something else is medically wrong. I'm afraid that if something was wrong I wouldn't be able to accept it and would feel guilty that I did something wrong. I really don't know what to do or think. Am I messed up for even questioning the potential love for my child?
