Why has my period changed since I started HRT?
Any time you add or change hormones in your body (including the use of birth control

competing with the same receptors as the hormones you make in your body, so more
or less of one hormone may cause an imbalance or rebalance, depending on the state
of your hormones prior to starting therapy.
