What are you talking about? Are you calling Mary's genitals the Ark of the Covenant? Such a belief is non-sensical and truly bizarre. Do you have any more weird and unbiblical allegories your church teaches?
There are a lot of scriptural passages that point to Mary at the ark of the New Covenant:
Just as the glory of the Lord overshadowed the ark in the tabernacle, the Holy Spirit overshadowed Mary.
THE ARK: “Then a cloud covered the tent of the congregation, and the glory of the LORD filled the tabernacle.” Exodus 40:34.
MARY: “And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee.” Luke 1:35.

In his narrative of the Visitation, Luke borrows heavily from references to the ark in 2 Samuel 6.
THE ARK: When trying to bring the ark up to the city, David said, "How can the ark of the Lord come to me?" 2 Samuel 6:9.
MARY: When Elizabeth greeted Mary she said, “[W]hence is this to me, that the mother of my Lord should come to me?” Luke 1:43. (Note the reference to the Theotokos.)

THE ARK: “[T]he ark of the LORD continued in the house of Obededom the Gittite
three months.” 2 Samuel 6:11.
MARY: “And Mary abode with her [Elizabeth] about
three months.” Luke 1:56.

THE ARK: David was
leaping before the ark as it was brought into the city. 2 Samuel 6:16.
MARY: At the sound of Mary’s voice, John
leaped for joy in Elizabeth’s womb. Luke 1:44.

The contents of the ark are all symbolic of Jesus, who was conceived in the womb of Mary.
THE ARK CONTAINED (1) a golden jar holding the manna (bread), (2) Aaron's rod which budded (the priesthood) and (3) the tables of the covenant (the word of God) Hebrews 9:4.
OUR LORD, CONCEIVED IN THE WOMB OF MARY is to us (1) the Bread of Life, John 6:48; our High Priest, Hebrews 5:10; and the eternal Word, John 1:1

Finally, in the book of Revelation we see the ark of the covenant, whose whereabouts has been unknown since the time of Jeremiah. Next we see the majestic woman with a crown of twelve stars giving birth to a child who would rule the nations. We don’t tend to read these verses together because of a chapter division but when they were written, there was no division. There is definitely a nexus between the ark and the woman (Mary) who gives birth to the child (Jesus).
“And the temple of God which is in heaven was opened; and
the ark of His covenant appeared in His temple, and there were flashes of lightning and sounds and peals of thunder and an earthquake and a great hailstorm. And there appeared a great wonder in heaven;
a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars.” Revelation 11:19-12:1.
