Just to add to the general picture of confusion (sorry), I find it doesn't matter how high my estrogen level gets (and it's been as high as 2000+ pmol during my menopause journey) I don't get sore boobs and bloating. But as soon as I go anywhere near progesterone (in this case Utrogestan) that's when it starts. Two or three days into the bleed and it's gone again. Surely that's exactly why the NHS doesn't measure estrogen levels routinely? If we differ this much in our reactions to the same hormone the only reliable thing to go on is symptoms, and unfortunately that makes it all guesswork, but I don't think we can blame the medical system for that. Individual reactions to progesterone are similar - some women can't tolerate progesterone at all, others need it continuously to feel well, but again I don't think blood tests are much use in working that out, it's one long slog of experimentation. Just more proof that God is a man, and I don't believe in him anyway so he can take his effing menopause and b****r off (sorry, don't want to offend those of you who are religious, but there are times when the luck of the draw just seems so...unfair) xxx
