Q: Is it possible to go back and forth between estrogen dominance and estrogen deficient?

A: Yes it is, although it can usually take some time and is not something that happens overnight unless one is artificially manipulated with hormonal supplements and medications. For example, a person can be estrogen deficient and turn dominant if too much estrogen is applied. When the estrogen is withdrawn, the flip side can occur.
