Hi and welcome to MM Millie02
Had you gone a full 12 months without a natural period or bleed before starting this HRT?
It's very normal to get some bleeding and spotting in the first 3-6 months on any conti HRT but if it continues beyond 6 months or is particularly heavy then this should be investigated. If you are still peri meno then the conti patches weren't appropriate, and would result in problematic bleeding, as you should then be on a sequi HRT regime. Sometimes there is a problem with absorption with patches and it you want a truly non bleed HRT combo then the Mirena with separate oestrogen as gel or patch is a good option.
I would carry on and see what happens - things may settle. Keep us posted. DG x
