A. From what you are saying from your history, it is unlikely that the combination and dosage of estrogen you are taking is causing any problem at all with your ovaries or the formation of a cyst. The only risks are those that are true for estrogen in general. Since women who take only estrogen and not progesterone appear not to appear to have an increased risk of breast cancer, and since you have taken your estrogen since your hysterectomy and have not waited 10 years to begin it, there should be no increased risk of heart attack. So it seems you should be able to continue the estrogen.

Why should I have a pap smear? What would they be looking for?
