What does it mean to 'play it safe' as a pregnant woman?
The Royal College of Obstetricians and Gynaecologists has produced advice to help pregnant women understand the relative risks of different chemicals to their unborn baby's health.
But the problem is there's very little evidence to say if these chemicals are harmful or not. The college says women who want to 'play it safe' should avoid them all even though they are in loads of products.
Could you avoid tinned food, sun cream and shower gel for nine months?
