Before starting hormone therapy birthcontrol, I would seriously look into it and not just the company's websites. The pill changes your hormone balance which can affect moods. Also when you are ready to have children, it can take months for the women to become fertile again. There is also some speculation that the because so many women are now on hormone therapy that the hormone in their urine is having environmental consequences.
The barrier methods (eg. condoms, diaphram) seem to be the safest and most effective.
As Salam alaikum wa rahmatullahi wa barakatu
