Thanks for your replies.
Hurdity, that's what I thought as well regarding not having much of a cycle left now. My meno doc never seemed bothered by the utro timing but did say my bleeds go on a bit longer than normal sometimes. The longest was 12 days and very scanty, the shortest was 2, it still varies each month. Surely if my cycle has pretty much stopped then the bleeds should all be the same length?
I keep a diary and noticed last year my bleeds were almost the same length each month and I was pretty much symptom free. The three years before that they were all over the place and I felt crap with very bad sleep.
The utro hanging around in my system for longer than usual definitely looks to be the likeliest cause of the late bleeds as you say, it does seem pretty rare though as I can't find info on anyone else taking so long to start.
I have never had any bleeding at other times which is odd as the patches have never completely controlled my symptoms, especially the sleep.
I'm taking 1 x 200mg utro.
