HRT is generally ramped up slowly. 3 month - check levels, check general health, check feminisation, adjust dosage. If meds are well tolerated, then the ramp up is quicker.
It wouldn't surprise me if your endos will only change the dose of one med at any one time - if something goes wrong, then it'd be more obvious which change was the cause.
If you hate taking pills, think about pellets once your dosage is stabilised.
