Been prescibed Dianette - worked well apart felt very sick for a month initially (due to the anti-androgens) then had from occasional pains and lots of blood clots (for a year). Was changed to Marvelon yet have constant period pain (yet no bleeding which is a bonus- been on it 2mths). Is there an 'ideal' back to back pill for endo or is everyone different? Is Yasmin better? Or is a contraceptive injection better? What do you find?
