Is a doctor prescribing you the estrogen? How many milligrams are you taking?
You are definitely hurting yourself by trying to do it on your own. Hormone replacement therapy is very complicated and can have a lot of unwanted and dangerous side effects if not monitored by a physician familiar with trans-sexual medicine. If you insist on doing this own your own, then I don't suggest using real estrogen. I would rather you use herb combinations such as Mammorex or Bust Rx; they mimic estrogen and cause the body to think it's getting estrogen, without all the dangerous side effects of true estrogen treatment that is not being monitored by a physician.
