Baby Chris is 19 Weeks Old

[This is part 20 of a multi-part series chronicling a pregnancy through the lens of "Baby Chris." Click here for other parts.] 

19 weeks after fertilization (21 weeks LMP), Baby Chris is 10.5 inches long and weighs just under 13 ounces; roughly the size of a large carrot. His or her movements are clearly felt by the mother, as "initial fluttering movements turn into full-fledged kicks and nudges."

If Baby Chris is biologically female, this week marks a significant reproductive milestone. According to the Endowment for Human Development:
By about 19 weeks, the number of oogonia within the ovaries of a female fetus peaks at approximately 7 million. From this point, not only does oogonia production end forever, but their numbers decrease to about 2 million by birth. These oogonia give rise to several thousand primary oocytes.
