Is there any saheeh report that says the du‘aa’ of a pregnant woman will be answered?

Is it true that the Duaa ofa Pregnant woman is accepted. I would
really appreciate if this can be clarified. Also, I would like to know
if there are any specific good deeds that I can do while I am
pregnant.
Praise be to Allaah.
After researching the matter, we have not found anything to indicate
that the du'aa' of a pregnant woman will be answered, either in the
marfoo' hadeeths (those that are attributed to the Prophet (blessings
and peace of Allah be upon him)) or in mawqoof reports (those that are
attributed to the Sahaabah).
But if the Muslim combines positive thinking about Allah, may He be
exalted, and certainty of His generosity with proper humility before
Him, then we hope that Allah will answer his du 'aa's and fulfil his
hopes.
It remains for us to note that the du'aa' of the mother for her child
is one of the du'aa's that will be answered, because the Prophet
(blessings and peace of Allah be upon him) said: "There are three
du'aa's that will undoubtedly beanswered: the du'aa' of one who has
been wronged, the du'aa' of the traveller and the du'aa' of a father
for hischild."
Narrated by at-Tirmidhi (1905). See also Saheeh al-Adab al-Mufrad, 372
Al-Mannaawi (may Allah have mercy on him) said:
"The du'aa' of the father for his child" is because he is truly
compassionate towards him and often prefers him to himself. As his
compassion is genuine, then his du'aa' will be answered. The mother
isnot mentioned even though the emphasis on her rights may indicate
that her du'aa' is more likely to be answered than that of the father,
because this is something that is well known. End quote.
Fayd al-Qadeer, 3/301
If a pregnant woman prays for her baby to be righteous, smart and of
good character, then wehope that Allah will answer her prayer.
