Forgive me for bursting your bubble, but it’s not approved by the Catholic Church.
I too, was once interested in this. Then I took a good long look at their website.
On their FAQ’s page it says:
“Holy Love Ministries is an ecumenical organization (which means it is for all people) and is NOT affiliated with the Catholic Church or any other denomination. We do not seek ecclesiastic approval under the Catholic Church. We are not a church, but an organization given a specific mission. The Rosary of the Unborn comes directly from The Blessed Virgin Mary and we are under Her direction regarding The Rosary of the Unborn. The Rosary of the Unborn is for all people. All people should be allowed to pray.”
Basically, they and the apparitions their “mission” has been based on are not approved by the Church, and they are not even interested in being looked at by the church. This is a HUGE red flag…in all VALID apparitions Jesus and Mary always tell us to be obedient to the Church and its bishops. Read up on Blessed Josefa Menendez or St. Faustina, for example. In my opinion, the rosary of the unborn is either 1) a huge scam to make money or 2) the direct work of the devil, appearing under the guise of Mary.
Bottom line: beware, and pray for the unborn with a normal rosary or prayerbook.
