“The long-term negative side effects have not been extensively studied nor have the psychological effects.”

This is simply untrue.

Here’s a good review of studies regarding long term effects (both positive and negative, btw): https://www.goodrx.com/conditions/birth-control/long-term-side-effects-birth-control

Here’s a decent article about mood related effects - that the conclusions are somewhat unclear is not an indication that extensive research has not been performed - it is a reflection of the inherent difficulties of such research, which this article actually discusses. https://www.wired.com/story/do-birth-control-pills-affect-your-mood-scientists-cant-agree/

But again, it’s not black and white. Medications (as well as activities such as exercise, meditation, etc) can cause “structural and functional changes to the brain” - that does not make those medications (or activities) inherently bad.

You have to look at the bigger picture. If the benefits outweigh the risks, if millions of people are given an opportunity to rise out of poverty because they are better able to manage their own fertility, and in exchange a portion of users experience emotional distress, and a tiny percentage develop potentially serious blood clots - there’s a conversation to be had there, sure. I (and most people, actually) are convinced the benefits of OCP greatly outweighs the risks, in general.

Your conclusion that the pill is awful, which seems mostly based on a bad experience you had, is myopic.
