This is a great article. Doctors use a lot of medical words with pregnant women and it can be very intimidating. Its very helpful to know that gravidity simply means the number of pregnancies a woman has had.
I was also very surprised to hear that 35 is "elderly" as far as pregnancy goes. In this day and age many women choose to have a career first and then have children in their 30s. I guess social norms don't really factor into biology!
