Hi and welcome to MM StripeyMaz
Bleeding in the first few weeks and even months on a conti HRT is quite normal - it can take up to 6 months before the bleeding and spotting stops. Reducing meno symptoms can take time and if you were very oestrogen deficient, then it can take at least 3-6 months before the benefits can be truly felt. Most women prefer to start with sequential HRt regime and put up with a monthly bleed, as this is often better tolerated than the conti HRTs.
You may get some bleeding when you stop the HRT but this should subside within a week.
If it's just aching joints that are causing you problems, then it's worth trying a diet rich in Omega3, calcium, Vitamin D and magnesium - also brisk walking everyday does wonders - I'm an ex professional dancer with terrible joints - I wake each morning feeling stiff and achey and the best way to ease the pain is by going for a long brisk walk.
If you are carrying a bit too much weight ? - so many of us struggle to keep the weight under control when meno hits

Loosing some weight and improving muscle strength can also work wonders. What ever you do - KEEP MOVING - don't sit down for too long.
HRT can help joints but it is about a whole range of measures and also finding an HRT that suits you. Perhaps try a sequential HRT e.g. Femoston 1/10, for 3 months and see how that goes? DG x
