I have had surgery twice now for endo, first time keyhole and 2nd time open surgery, and I have severe endo. I had surgery 1st time oct last year and again july this year. I have been put on the zoladex injection every 28 days. I am due my 3rd one next week. I am concerned as I have started bleeding this time and am experiencing a few clots. My husband and I had intercourse wed and I started spotting and then early this morning I started bleeding, it has been light through the day. My scar seems to have gone quite hard again. I feel quite well in myself and have no pain. Can anybody help please?
