You haven’t said why your GP wanted you to try stopping. Do you have any particular risk factors?
I would disagree with the ladies who say there is NO risk.
Studies have shown that some estrogen is absorbed systemically and the estrogen only product is unopposed by progesterone. However only a very small amount is absorbed and for increased breast cancer risk people like me it is generally considered safer. Some studies have found no increase in cancer, while others have found an increase in cancer. Safest is said to be when younger like you and for a few years.
If you have had estrogen dependent cancer, you can take it, but it won’t be the first line of recommendation.
Due to having had a precursor to breast cancer I’ve gone off systemic HRT but am using vagifem.
