Here is what is going on this week in a 9 week old fetus (this is not for twins, as I can't find exact descriptions for twins this early), so this will have to do for now.
How your baby's growing:
Your new resident is nearly an inch long — about the size of a grape — and weighs just a fraction of an ounce. She's starting to look more and more human. Her essential body parts are accounted for, though they'll go through plenty of fine-tuning in the coming months. Other changes abound: Your baby's heart finishes dividing into four chambers, and the valves start to form — as do her tiny teeth. The embryonic "tail" is completely gone. Your baby's organs, muscles, and nerves are kicking into gear. The external sex organs are there but won't be distinguishable as male or female for another few weeks. Her eyes are fully formed, but her eyelids are fused shut and won't open until 27 weeks. She has tiny earlobes, and her mouth, nose, and nostrils are more distinct. The placenta is developed enough now to take over most of the critical job of producing hormones. Now that your baby's basic physiology is in place, she's poised for rapid weight gain.
We have moved from sesame seed, to lentil, to blueberry, to kidney bean, and now the grape! I love the way this site relates everything to food! Now that I am regaining my appetite food finally sounds ok! At first I just wanted to eat watermelon all the time. I still don't want any Mexican food, which is not normal for me at all!
Happy 9 weeks babies!

Pop and I are so excited! We have to plant 2 more trees before New Years!
I forgot how amazing the first trimester is. By the way you look fabulous!
Hey Jill,
I-Am-Pregnant.com has a whole section devoted to week-by-week development for twin and other multiple pregnancies! It's not as well-designed as babycenter.com but it's still pretty good if you want to check it out!
You can find it here.
I'm glad you're feeling better!!
