UK IVF induction offered at 40 weeks

Yuliya
Hi all, I'm 36+3 and Dr offered to induce at 40 weeks. I'm to book sweep and stretch with my midwife tomorrow at around 39 weeks. ( NHS funded) Nobody explained why I need to be induced. The general idea is they know the precise conception date and don't recommend to go past it. Anyone been in the same situation? Il
