[This is part 16 of a multi-part series chronicling a pregnancy through the lens of “Baby Chris.” Click here for other parts.]
Fifteen weeks after conception (17 weeks LMP), Baby Chris is five inches long and weighs five ounces—about the size of a turnip.

[P.S.—My apologies for the tardiness of this post; Baby Chris updates usually come on Mondays, but I was at a retreat center with unreliable internet for the Louisiana Right to Life PULSE leadership program for teens and young adults. Other than the internet issues, it was a wonderful experience! I expect great things from the next generation of pro-life advocates.]
