Duas for safety of child and mother during pregnancy

FALLAAHU KHAYRUN H'AAFIZ'AW WA HUWA ARH'AMUR RAAH'IMEEN

ALLAAHU YA-LAMU MAA TAH'MILU KULLU UNTHAA WA MAA TAGHEEZ'UL ARH'AAMU WA MAA TAZDAAD WA KULLU SHAY-IN I'NDAHOO BIMIQDAAR

But Allah is the best of guardians; and He is the most merciful of the merciful.

Allah knows what every female bears, and that which the wombs fall short (of completion) and that which they exceed. And every thing with Him is measured.
