It is usually sensible to give each type of HRT you try around 3 months unless you react really badly to the progesterone.
It is also sensible to start with a low dose on a sequential regime so you can tell if the progesterone suits you or not. Often women start with the combined patches which are medium dose and this can be a big hit of hormones too quickly.
Symptoms like flushes can reduce within the first few weeks but if you start from a very low baseline then it can take longer.
Low mood, fatigue, dry skin, aching joints etc can take longer to improve.
It is trial and error for many women but most women will get benefits with few side effects.
I think it is unreasonable to expect to feel good every day but basically the benefits of HRT must outweigh any side effects. DG x
