I have endometriosis and it causes me quite a great deal of pain. My obgyn doctor said it's cheaper to treat the symptoms at this point and birth control helps. I have bipolar though and the general prescribed one made me so manic, I think it was estrogen based. Has anyone had the subdermal implant or a iud? Would a different form of birth control pill help? Also I'm on lamictal which is a anti seizure med and some birth controls can reduce the effectiveness of lamictal.
