Blueberry Week 7 weeks

Week 7 has been completed. Now 7 weeks and 3 days!
Whats new this week. Baby/embryo doubled in size measuring 1/2 an inch, the size of a blueberry.
The arms and legs are starting to develop, looking like real small paddles. The brain is still continuing to develop as well and has both it's hemispheres.
If I were to have an ultrasound you would be able to hear the heart beating! I won't hear or see it until my next appointment on the 27th of January, so I'll have to wait a while.
I'm still doing ok. Nauseated but not throwing up. So I have that going for me. Other than that all is well.
