Contraceptive app hit with complaints after being blamed for 37 unwanted pregnancies

Excerpt from this article:

Natural Cycles, a contraceptive app that became certified in the EU as a form of birth control, has been hit with a complaint after being blamed for causing 37 unwanted pregnancies, reports Swedish agency SVT. Södersjukhuset hospital in Stockholm reported the app to Swedish regulator MPA (the Medical Product Agency), after 37 women visited the hospital for an abortion after becoming pregnant while using Natural Cycles.

The app uses an algorithm and measures factors like temperature to determine the period when a woman may be fertile.
