First Post - Feelings about TTC baby #1

Husband told me the other day (after several intense weeks of my baby fever bantering) that he is ready to actively try and get pregnant!! We both agreed we wanted to get pregnant and have our first in 2016 (the reasoning is long and requires its own post entirely) I could barely believe it when he said we can start trying next month! I was so happy, but what I didn't show my husband was the fear I felt almost instantly.. I had this feeling of "Omg can I actually handle this?" It's weird because I would think that is the feeling a mother would have the first moment they know that they are carrying a child, but I am not pregnant.  I have wanted to have a baby for years and have discussed this with my husband for years (4 years to be exact). Now that he has finally said yes he's ready - is the first time I feel unsure I am actually ready. Is this normal? I am very excited to plan this baby, I was/am curious if my initial feelings/ reaction to actually begin TTC was something anyone else shares/ shared. Happiness and Baby Dust to All!
