You should be more concerned with the psychological effects of birth control, which in my opinion are drastically understated and underesearched. We are toying with the hormones of tens of millions of women and the vast majority are unaware of the potential differences in decisionmaking and behavior.
There are secondary effects as well, for example, women have been shown to select for more dominant, aggressive men when fertile and meeker providers when not - how might that shape our social landscape, if a sizable proportion of women are kept permanently in a hormonally induced infertile state?
