Had everything took out during my hysterectomy is a 2mg estrogen pill to much?

Maybe: Typical doses for oral estrogen are 0.5, 1 and 2mg per day. Most physicians start women at a lower dose and then increase the dose if their symptoms are not well managed. There's likely no harm at the 2mg dose. Depends on how your body is reacting and responding to the loss of your ovaries. Every woman is different. If you are concerned, have a conversation with your doctor about your symptoms.

Probably not: I am assuming this his Estradiol 2mg tablets. Your doctor can monitor your labs and adjust as needed based on symptoms and labs. If "everyting was removed", you may also want to keep an eye on your testosterone going forward. Testosterone in women can drop over time when ovaries are removed. This can make bones weaker, reduce libido, etc.
