The following prayer points against barrenness and infertility have been a blessing to many families. I would encourage you to trust God Almighty and totally depend on Him, irrespective of what the doctor or any other person has diagnosed.
Genesis 1: 27, 28:
27 So God created man in his own image, in the image of God created he him; male and female created he them.
28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth. (KJV)
The Word of God declares that God commanded the first family to be fruitful and multiply. God cannot command you to do anything He has not empowered you to do. You must realize that He has already made provisions for you to be able to succeed in whatsoever He has commanded you to do. God cannot lie. The Scriptures cannot be broken. Throughout the Bible, there is nobody who truly served God and remained barren.
Begin by giving thanks and praises to God in songs. Praise and worship Him.
