Michelle,
Congrats! All I can tell you is to take care of yourself. Do those things that calm and relax you. I enjoy a cup of herb tea and to create something, (scrapbooking or homemade cards.) Try to keep yourself busy so you don't have time focusing on your fears. Sorry I couldn't have been more helpful. Hang in there and let us know how things go for you!
Hugs,
Melissa B.
