i think you should go and get a second opion before you start haveing any kind of estrogen or proestrogen. as per i had a blood clot almost 6 yrs ago and my drs would not consider any hormonal therapy for my medical problems. i have gone to others and they too would not consider hormonal therapy for me. my best advice for you is to go and get a second opion from someone else and see what they would do. my clot was just from a fall, not any real medical reason to have one. hope this does not offend or scare you in any manner.. hope you can get another professional to look into your medical matter for you. hope this reaches you in good health.if you have any further questions please feel free to email me.
