To get it over with....Susan's Forum policies *blah blah blah* does not advocate self medicating *blah blah blah* do not post dosages *blah blah blah*....
Seriously though, you really should go to a Doctor to have them check you out. That is how you can get a blood test done. They have the medical experience to interpret the test results and advise the best course of medication for you.
Every body is different and especially since you are self medicating, results will vary even more widely than if you were getting your meds the right way (Dr prescription). Already there is too much variability to say just when you should start to notice breast growth but add in the fact you are self medicating, you just are introducing more variables into the mix and no one can really say definitively when you should expect to start to see changes.
Get yourself checked out by a doctor, stop self medicating, and be safe.
