Was the Virgin Mary God's consort/wife, as Saraswati would be the consort of Brahma? No, she was not.
A devout young Jewish woman, a human, she was chosen by God to be the vessel for His Son when He came in human form as the Messiah, Jesus Christ. She conceived through the Holy Spirit, not through the normal physical process. She later gave birth to Jesus, who was born humbly and raised as a carpenter's son, with no worldly advantage in His origins.
At the time, she was betrothed to Joseph. This was the first step (Kiddushin) in the two-step Jewish marriage process. It meant that she was technically married, but had not yet gone to live in the house of her husband. It also meant that she and Joseph should not be physically intimate; that was reserved for later, after the Nisu'in portion of the marriage. (These two parts are usually combined nowadays.)
So although Mary was obedient to God and innocent of wrong-doing, this would have put her in a very awkward position. Family honor, particularly regarding a woman's virtue, was a very serious matter. By law, Joseph could have had her stoned for her pregnancy. Instead, he believed God's messenger, who reassured Joseph in a dream, and chose to shield this devout woman from disgrace. He took her as his wife, but he waited until later to have intimate relations with her. (Some Christian denominations believe Mary was always a virgin, but there's no particular reason that need be necessary. The Bible indicates she had other children later on.)
In any case, Mary was not God's consort. Rather, she was an honored human servant of God who is remembered for her faithfulness and obedience ... and her joy in it:
“My soul glorifies the Lord
and my spirit rejoices in God my Savior,
for he has been mindful
of the humble state of his servant.
From now on all generations will call me blessed,
for the Mighty One has done great things for me—
holy is his name.
His mercy extends to those who fear him,
from generation to generation.
He has performed mighty deeds with his arm;
he has scattered those who are proud in their inmost thoughts.
He has brought down rulers from their thrones
but has lifted up the humble.
He has filled the hungry with good things
but has sent the rich away empty.
He has helped his servant Israel,
remembering to be merciful
to Abraham and his descendants forever,
just as he promised our ancestors.”
