The intrauterine implant (ex. Mirena) should less affect blood levels of hormones than do the bc pills, to less affect mania and depression associated with BP. This is actually recommended for BP patients and those with endometriosis. It is expensive though and some insurances do not cover it; do some research about this as well as the risks with having an implant. Talk to your doctor further as well if you have more questions too. This may be a better choice though than BC pills or GnRH anatagonists.

Raspberry leaf tea has been shown to help ease symptoms of the pain and cramping associated with uterus for with PMS, periods, and endometriosis. It does not affect the formation of endometrial implants, adhesions, or the prevention of it. Evening primose rose oil (comes in capsules) also helps block prostaglandins to ease with cramping and bloating as well.

I hope you find some relief soon.
