I have only really been tracking my cycles since I was trying for a baby before I was diagnosed with endo s3/4. I have been on a course of prostap which I had my last injections 29/08 my first period after this (which was horrendous) was on 8th September - I never had another one until 14th December. its not been 38 days since period and I still haven't come on. me and my partner have unprotected sex as we have been trying for a baby for a long time. However not actively at present due to so much disappointment, and being told by consultant that would be impossible to conceive naturally. However I never seem to hear of people with this level of endo having such sparse periods . some months I can have one every 20 days with break through bleeding but then others I've gone 45 days plus without a period. I did a preg test on Friday which was neg. it breaks my heart to see this every time so was just looking for other people who have the same irregularity? if so have they had any other conditions diagnosed alongside endo which are the cause?
