Hi Shanp
I'd stick with the Femoston sequi 2/10 for at least 3 months to see if things settle.
A good non bleed option would be to have the Mirena fitted and then use Oestrogel alongside.
Some bleeding or spotting is quite normal in the first few weeks, or even months, on any conti HRT.
It's trial error I'm afraid - look under TREATMENTS on this site to get clued up. DG x
