Besides the ultrasound, we have maternity homes, parenting classes and lots of resources for the women. Often informing them about the help available will show them that they can carry and be successful.
Since about 15 - 20% of pregnancies end in a miscarriage, we can save woman a lot of pain if their pregnancy wasn't viable anyway.
God bless you and strengthen you in your work.
Have been in those same trenches many years myself. So has my wife.
Some day the Master will say "Well done, thou good and faithful servant."
Then you'll see the faces of those who lived, and it will all be worth it.
Press on.
