My little miss was (is LOL) an IVF baby & she was born at 41 weeks, 3 days. There's no need for bub to come early (or exactly on time) just because you know the exact date they were conceived. Some babies need longer to be ready to be born, sometimes we just cook our bubs longer than other people. It all varies based on mum & bub.

Besides bub may surprise you & you could go into labour tomorrow
