Hormonal Birth Control Methods

My daughter is taking a hormonal birth control, it is Sprintec. The pill is to stop her menstrual cycle all the way. A few medications have interfered with the birth control, making her have her period. Will the MMS affect her birth control?

TBD - I will tell you that Mark Grenon feels that MMS will inactivate birth control because one of his daughter-in-laws got PG while "on BC" - I don't know. This was a sample of 1 (to the best of my knowledge) - so it's possible something else happened, since people also get pregnant while on birth control and not on MMS.

Just something to keep in mind.
