My sister got away with no one know she was pregnant until nearly 7 months, and she only weighs just under 100 lbs. Everyone carries babies differently. Lots of times, boy will carry deeper into the stomach cavity causing the rear end to spread and girls will flop forward. Same sister, pregnant with girl 2 years later, same weight at start of pregnancy... looked 5 months pregnant at 3 months.
Stupid stupid “journalists.”
Oh, and the one of her “three weeks before giving birth”, she is leaning over, causing her tummy to shift inward.
"Basketball" (girl) vs. "Football" (boy). In the days before ultrasound pics, this was the accepted guessing method...
