I had my 18 week appt. today. Baby's heart beat was 160 and the doctor said I am measuring right on track. He did say I won't be hiding the pregnancy for long. I have a very small bump for 18 weeks, but he said my strong abdominal muscles are holding everything in. My 20 week ultrasound is next Thursday night. I'm having it early due to switching jobs and insurance. I think it's finally becoming real that I'm having a baby after a mmc at 6 1/2 weeks in Feb. Let's hope the anxiety lets up now.
