Why are we still struggling to get contraception right?

As the pill becomes available over the counter and free of charge
in England, Madeleine Finlay talks to science correspondent Nicola
Davis about the problems women in the UK face in getting access to
appropriate contraception, and how unwanted side-effects and lack
of support have led to a rise in the popularity of fertility
awareness-based methods. She also hears from Katie about her own
journey trying to find the right contraception for her body. Help
