Birth Control for the Bipolar

I was diagnosed as Bipolar Type 2 a few years ago and have since been on different combinations of psychiatry medication.

As a result of this, my gynaecologist strongly advised against using any forms of oral birth control - because they are a depression trigger.

A couple of months ago I switched from allopathy psychiatry medication to ayurvedic tablets and I’ve seen a significant positive difference in the way my mind and body respond to it, but I would still like to be on birth control.

Any thoughts on other forms of female contraception I could look into?
