I am 17 weeks pregnant, and all of a sudden, i feel like I have cold feet. I am nervous and cannot actually believe I am pregnant. I can’t believe this is happening. Everyone always makes it sound so difficult. I feel like I am nowhere fit to be a mother. What if I mess up? I was so excited for this a week ago. Now I cannot believe this is happening. Any expecting moms out there who feel the same way? Is this normal?
