Thanks for replying Hurdity, you always explain things so clearly.
I agree that it might be I'm just not producing that much oestrogen (despite 4 pumps) my last oestrogen level was 655, which Prof Studd 'wasn't high'.
I'm not sure whether I do ovulate? This month I felt wired and jittery on days 12-13 of my cycle, and seemed to have more clear mucus than normal. So perhaps I did?
But it quickly went away, then I was fine for a week until I started Utro, then everything went very downhill within a few hours.
I am STILL feeling wretched and horribly anxious, and it's been 7 days since finishing Utro, and my bleed finished yesterday.
How much longer will the progesterone keep on poisoning me like this?
I intend to follow my GPs advice and just use Utro every 3 months. It will be interesting to see how I react to it in 3 month's time, and if in the meantime I react to when I get my own period.
