Opinion poll: when is the best time (before or after giving birth) for health professionals to ask about your future family planning/contraception plans?

We have been asked by JPUH to ask local bumps and mums when they would prefer to discuss any requirements for contraception after their baby's birth. Did you know that you can get pregnant again just 3 weeks/21 days after giving birth? (if you feel like it sooner than we did anyway!) And that's even if you're breastfeeding. Its also worth knowing that for those considering sterilisation, this can be done as part of a Caesarean section, saving a separate operation. 

What do you think?
