Butterflies

We got married in July and I came off the pill 2 months ago. I had my first period last month. This month we had sex on the 2 top days for ovulation! I am due my period on Saturday (if they r regular) I am so desperate to be pregnant, when I think of it I get butterflies in my stomach! I don't know how I will cope if it takes us a while, months, years!!!
I am terrified of childbirth but it is like I am longing for a baby! xxx
