Almost ½ way panic

I feel like i just got pregnany yesterday. Am no where near ready to have this baby. How did time run so fast? Will be 20 weeks in less than 4 weeks. Why do i dread having a baby? Was same with my first. I wouldnt mind being pregnant for 2 years honestly. Maybe because am alone amd my husband works aeay from home so i get to do everything alone. I dread parenting even more because i dont know how i will handle two. But i didnt have the luxury to wait longer to ttc. Guess i need encouragement that i can do this.
