Thanks to you all for your best wishes, for my birthday. I had a ball and the girls, in particular, were so supportive and I had lots of girly presents

However, the male half of one couple, could't cope with, the idea of coming. It is a warning, that the road ahead will have its bumpy patches.
Alexis,
If I am anything to go by, you should reach a B cup, at least. Given that your tostesterone levels will be at their height, you might wish to add Black Coshash, as an anti androgen, wild yam, to mimic progesterone and make sure your source of PM is 100% pure.
What you will need, in huge abundance, is patience; just remember how long it takes a girl to develope her boobs. TS girls, put on prescribed hormones ans anti androgens, take 2 years for boobs to fully develope; so look at this as a 2 year project. In reality, the slowness of progress is a good thing; it allows you the time to adjust to the reality and implications, of having boobs.
I am a little concerned by your question, about stopping and re-commencing taking PM. If you have any doubts about what you are doing, do not go down this road, as the reality is that, once you have boobs, they are for life.
I think you should glean as much information as you can, about transexualism and the issues around coming out. At best, you may get to understand yourself better and, even if you are not TS, once you reach a B cup, you will have to confront many of the same issues. I would not recommend taking a break from PM, as I had to, once, for reasons beyond my control and, despite substituting fenugreek for 2 weeks, it took massive poses of PM to get things going again.
Remember that most TS girls only make a B cup, on prescribed hormones, so do not get over ambitious; a b cup in 2 years is a great result.
I hope you get this right and, if you go ahead, best of luck sister, because if what you desire, is to be as close to being a woman, as is possible for a genetic male, the rewards are overwhelming. If that is not what you want, please take care.
Chrissie
