Wondering how common it is to have some bleeding after starting topical oestrogen, or if I need to go back to the GP. I had a urology appointment where the consultant recommended estring for some urinary symptoms, which I started about a week ago. It's been OK so far until some bleeding yesterday and today, bit like a light period. I haven't had periods for 2 years but am not on systemic HRT yet for various reasons. So this is the first hormonal thing I've had. Prior to the urology appointment, I had a TV scan for some pain, which was clear apart from a very small ovarian cyst; I had a CT as part of the urology appointment, which was also fine. Blood tests like ca-125 and others have been fine too. So likelihood of any pathology is pretty small I think. But I know they are cautious about post-menopausal bleeding. It seems fairly likely that it's caused by starting the topical oestrogen, so I wonder if the GP is likely to do anything further, given I've already had various tests in recent weeks/months, which are probably the tests that would have been recommended otherwise.
