I don't see this on my married female friends pages who are preggers so I'm guessing this is a way for women who took raw loads and got knocked up out of wedlock to feel better about themselves and rationalize their taking of raw loads for their Christian FB family/friends?
Also OP is knocked up out of wedlock but recently came hardcore back to her Christian upbringing and all of the comments are from friends of hers who got knocked up out of wedlock and are now single mothers or raising their kid with some other guy.
