Would this suffice for First Saturday devotion?

[GoodMorning]

Okay, so for one thing I know there is a requirement of saying five decades of the Rosary in reparation for the Immaculate Heart, but there is also a requirement of meditating fifteen minutes on the Mysteries of the Rosary. Can I just say fifteen additional mysteries of the Rosary (like from First joyful to final glorious) to suffice for this? I would have a hard time doing so otherwise. Or maybe someone has another suggestion??

Also I am a teenager who does not like to inconvenience his parents without just need. Would it suffice to receive Holy Communion the following day (the Sunday following)?

The requirements for First Saturday Devotions are to do as follows on the First Saturdays of five consecutive months.

1. To confess and receive Holy Communion on the First Saturday of the Month. The confession doesn’t necessarily have to be on the First Saturday, as long as Communion is received in the state of grace. Yes, Communion must be received on Saturday, not on Sunday. Sunday is the Lord’s Day, Saturday is traditionally Our Lady’s Day.
2. Recite the Rosary. (5 decades).
3. “Keep me company for fifteen minutes while meditating on the mysteries of the Rosary.” This is in addition to the time it takes to recite the Rosary. Maybe you could read the bible passages related to a particular mystery and ponder them.
4. All with the intention of making reparation to the Immaculate Heart of Mary.
   There are five kinds of offenses and blasphemies against the Immaculate Heart of Mary, namely: (1) blasphemies against her Immaculate Conception, (2) against her perpetual virginity, (3) against the divine and spiritual maternity of Mary, (4) blasphemies involving the rejection and dishonoring of her images, and (5) the neglect of implanting in the hearts of children a knowledge and love of this Immaculate Mother. Five, hence the five consecutive months in this devotion.
