Be careful cycling hormones. Our bodies are not meant to switch back and forth on cross sex hormones. I recommend you consult your doctor.
Many times hormones are started and reduced gradually allowing time for our endocrine system to adjust. Quick changes to HRT can cause issues.
Yes, you can go back on HRT at a later date.
There is no judgement, transition is difficult and if you are not sure it is wise to wait.
