Don't know if I'm posting in the right place but I have suffered with PND and am very up and down with depression (My Dad has bipolar disorder and my brother so think I may have it too). My ups and downs are very much exacerbated by my menstrual cycle and feel my blood boiling round in me just before I am due on. A friend has suggested I try the morena (is that right?) coil. has anyone got any experience of this helping them?
