What is the waiting period that must be observed when the waiting period of a pregnant woman (delivery) coincides with the waiting period for death (four months and ten days)?

The waiting period (iddah) for a woman whose husband has died and who is not pregnant is four months and ten days, based on the Almighty's saying: "And those of you who die and leave wives behind, they shall wait on their souls for four months and ten [days]." (Quran 2:234) As for a pregnant woman, her waiting period is until she delivers her burden, based on the Almighty's saying: "And for those who are pregnant, their term is until they deliver their burdens." (Quran 65:4)
