I would look over your cycle history and see if you have estrogen related sides etc, if not there is no need to introduce it, but if you are prone 10mg ED will be fine and should give you a good balamce.
Sides as in, itchy nips or sore nips? Or emotional sides?

Ask yourself have you had estrogen related sides in your past cycle history? if not just have an AI to hand when you cycle just incase you do see signs appear in this cycle, but if you have struggled with E sides then start one straight away along side your cycle,
