Abortion was made legal in the whole country here in 1973, but it only covers until "viability" of the fetus. If she didn't figure out until later that, she wouldn't have legally been able to have an abortion (though that's not saying it would have stopped her). Perhaps she didn't want one for whatever reason. Just because a woman supports the right to choose (or even if she's had one in the past) doesn't necessarily mean that's the choice she'll make every time.

There are lots of options here and we won't know until season 11 what the actual circumstances are.
