I have two grandchildren who were both conceived while their mother was on the pill. Since we all live in Canada, abortion is always an option, but this is what "pro choice" really means. I have a fifty year old son who was a "surprise".
Birth control in the real world isn't nearly as reliable as Big Pharma keeps telling us. Many women can't take the Pill, and I was one of them. It made me violently ill, as did pregnancy.
You'd be amazed at how many men refuse to get a vasectomy. It's a virility thing.
A fetus isn't a "human life". Living humans can breathe. A fetus is a potential human life, but even 1/3 of all of these little guys and gals don't make it out of the first trimester, because a lot can got wrong, not just for the gestating fetus, but for its mother too.
We don't believe human life is dispensable. Virtually every woman I know has had a unplanned pregnancy and for most of us, especially in Canada where we have paid 1 year maternity/parental leave, child tax benefits for low income families, and universal health care, choose to continue those pregnancies.
But I've also had difficult pregnancies, and high risk pregnancies that required surgical intervention. I carried a dead fetus for at least two weeks. In Texas, they would call the surgery an "abortion", but the fetus had been dead for weeks. They would have sent me home until there was an infection, which might end forever the possibility of my having another baby.
People who aren't doctors dealing with pregnant women, should never be allowed to write laws about reproductive health care.
And the late term abortions are the ones which are most medically necessary, and must be preserved.
