Every day, as my belly grows, so does my panic ? I'm scared for the baby (it's normal to feel anxious, here it's not that big of a panic) but overall, from the unknown, I don't seem ready at all, how is everything going to happen? What kind of mom will I be? I've been working since I was 19 and can't imagine myself in maternity leave...
