21 is a fine age to start. The rule of thumb is that teens should not tamper with hormones because it will interfere with their normal growth process, but you are fine and are two years out of your teen years and, if you say you hit puberty pretty early, I say you are fine.
I am not really great at reading those test results from the online hormone test you posted there, haha, mostly because I do not trust it at all, so I am not going to consider it when I make my answers. I DO think it is important for you to get your tests done before you go and mess with your hormones, though. Trust me, it is worth it. Also, I honestly do not know much about birth control especially since I have never been on it, but I can give you only what I think I can answer until a more knowledgeable forum member wants to contribute...
PM is most certainly fine to take with BC. Actually, if you take it with BC, there is no need to cycle (yey for you!) since you do not get your period. Check out Bonita's PM program. Since you do not know your hormone levels, simple is better. Bonita went simple also, she did not know her hormone levels and simple worked for her.
Don't bother with Wild Yam, as there really has been no proof of it converting to progesterone in the body ( http://umm.edu/health/medical/altmed/herb/wild-yam#ixzz2gcG5pjo4 ). Maca is an herb that is kind of a mystery herb, as it is really unclear how it actually works: all we know is that it balances the hormones. Goat's rue is a good choice for increasing prolactin.
From what it sounds when you ask about BC lower testosterone (which I don't know about myself), you want to raise your testosterone a bit to get a booty (you mentioned hip-to-waist ratio)? If you want to raise testosterone, maca should work for you by simply balancing out your hormones. There is also tribulus, which is also a possibility. I will add here, however, that neither have been proven to raise testosterone levels but it's worth a shot.
I don't think you should consider using PC cream since you are on BC as they both contain a good amount of progesterone. I do not know how much Progesterone is in Red Clover, but for sure PC is strong and BC is probably giving you all that you need when it comes to Progesterone. So, with just your BC, you should be set (but, again, this is all without knowing your actual hormone levels).
You are CORRECT about not adding any other phytoestrogen to your program if you plan to take PM. PM should, honestly, be enough! It is the strongest phytoestrogen and a little will go a long way (IF it is what your body needs).
As for the cleanse, take it for a week
And you'll be set.
I guess to answer your "dosage and brands" question, you will need to asses the answers given to you first on WHAT herbs to take, and then we can go from there once you narrow it down!
