I agree its probably just the pill messing with her body and delaying her period. Go get a home pregnancy test and have her take it to help ease your fear and she should probably make an appointment with her gyno to see if maybe a different form of birth control would work better for her and have less side affects. The dosage could be off too. She may need to be switched to a low dose pill or vice versa.

i wouuld take her too a doctor too get checked ouuut or take a test.

Not from being fingered. Its probably the pill messing with her
