Is this normal?

I have a nine yr old who is my world. I'm now 9 weeks pregnant with 2 ND child and I'm scared out my mind worried stress confused. I catch myself crying a lot at just the thought of me being pregnant.

And as much as I'm not ready for this I can't see myself getting an abortion.

Is it normal to feel these feelings being up then down? Worried about baby worried about the unknown?

Am I the only one feeling this way?

I didn't really feel this way when I was 17 pregnant with my son. But now I'm 27 and I'm just so all over the place emotionally.

I don't understand it...
