The important part is §218a which declares the situations in which abortion is legal. This is not something like prosecutorial discretion, it's still a matter of law.
Most notable: "The pregnant woman does not incur the penalty specified in section 218 if the termination was performed by a physician after counselling (section 219) and no more than 22 weeks have elapsed since conception"
You seem to have made a quite unlucky typo there. It's 12 weeks since conception, not 22. We are not that progressive.
