I had 1st decapeptyl injection 6 weeks ago, the first couple of weeks were awful, as expected, but since then I've been great (apart from headaches which I can put up with!) Today, I've woken up with a good deal of pain, and some bleeding. Has anyone else experienced this? I have had decapeptyl a couple of years ago, and did have a lot of spotting throughout, but no pain. Does anyone know why I suddenly have pain and bleeding? Thanks very much.
