I am sure you want to know what's going on with the baby!
You' baby's fluttering heart would show up on an ultrasound performed this week (it did...it was 171 beats per minute). He or She is between 0.56 and 0.8 inches from crown to rump - or about the size of a grape (my doctor said the baby was 1/2 inch long) - it's liver is churning out large amounts of red blood cells and will continue to until the bone amrrow forms and takes over this function. Week eight marks the beginning of a very busy developmental stage: its face continues to change as the easrs, eyes, and the tip of the nose appear; the intestines start to form in the umbililcal cord, and your baby's teeth begin to develop under the gums.
I promise I won't post these weekly, but since you saw the ultrasound now you can know what all is going on in there, too! I get an email every week from PregnancyWeekly.com telling me what is going on & showing pictures from other ultrasounds. It's pretty informative & interesting, especially since I have never gone through any of this myself before!
