Barging in from another board; from what I understand:
Depending on your age/relative fsh you want to simulate as close as possible to your target hormone level so if you are younger or have a lower fsh, you'll want a higher dosage and that could be bcp. Loestrin/Junel is 24 I believe. Though keep in mind, hormones that go through your digestive system tend to be harder to tolerate than ones delivered through the skin/patch.
Some times it takes a while to figure out the right combo. I am trying to get the vivelle dot and 100mg of prometrium but geez, all the doctors seem to have their own protocol to "push."
Best of Luck!
