Do you think hormonal birth control is harmful?

I’m usually very pro science and believe in the medical system. However I sometimes wonder if hormonal birth control is causing reproductive problems in women. If you can use tracking apps to monitor fertility wouldn’t it be safer than taking pills that mess up your hormones?

I wonder if the decline in western nations birth rates is somehow related to this?
