Hi Deeknitty and welcome!
Conventional wisdom says that it takes a minimum of 3 months to settle into an hrt regime and for some of us it takes longer. If you are trying to balance oestrogen and progesterone levels on a continuous regime, it is quite common to get what is called "break through" bleeding, so don't worry at the moment, I would say perfectly nomal.
