Full of confidence, I have recourse to thee, O holy Virgin and Martyr St. Margaret! I implore thy powerful intercession with Jesus Christ and His Virgin-Mother for all women in the state of pregnancy. Intercede for them, that they may carefully preserve their babies from harm and, by their pious conduct, assiduous prayer, and the offering of good works to God, may obtain many graces for their souls.
Have compassion especially on her who is now in the state to require thy loving assistance. Espouse her cause. Obtain for her alleviation in her pains, comfort in her sufferings, and a living healthy child, for the glory of God and the joy of Holy Church. O most loving and thrice-blessed Martyr, thou who art so rich in merit, present to the Heavenly Father all the sufferings and tribulations thou didst endure for His love. Unite all to the merits of Jesus Christ, to those of His Blessed Mother, and of all the saints in heaven. Offer them for this poor, suffering mother, O thou who hast lent thy assistance to so many in similar need! Obtain once more the favor of heaven for this mother and her unborn babe, Oh, no, good St. Margaret, thou wilt not abandon us! Thou wilt obtain a favorable answer to our request, by thy intercession at the throne of Divine Mercy. We thank thee beforehand for all thy goodness. In return for all the favors thou wilt obtain for thy clients, we offer thee all the praise and love given thee by saints and angels of heaven; but, above all, the love bestowed upon thee by Mary, the Virgin Mother, and by the Lord of glory, Jesus Christ Himself, as well as all that they will continue to shower upon thee for all eternity. Amen.
Prayer to St. Margaret for a Woman in the Pangs of Childbirth
