On day 15 of the cycle, India looks at fertility and the process of trying to conceive - and explores the tragic reality that not all pregnancies are successful. Dr Dornu Lebari takes us through a fertility consultation, and discusses the stigma that surrounds reproductive health. Dame Lesley Regan speaks with India about early miscarriage.
