Girls please facilitate beside my friend (lady problem)?

ok so my friend missed a period finishing month but this month she has have it of almost two weeks and still going normaly her periods one and only last for more or less 5 days she is freaking out she doesn't have a mom and she doesn't wanna update her dad unless she is sure that something is wrong i was wondering is this ordinary she is freaking out on the phone with me as i type but i dont kno what to put in the picture her is it normal? not really.
but it depends on profusely of things. is she sexual active would be first. and how long have she been getting her period in standard? it's not unusual for it take 2 years to inaugurate a normal template.
if she's just beneath stress or on new medication, afterwards this is a pretty standard thing to evolve.
in short, i'd recommend she confer to the school nurse or a trusted elder female. they can break things down for her and even abet her get within contact with a nice doctor, and detail her dad what's going on too.
If she is sexually active, it's possible that she get pregnant and has very soon suffered a miscarriage. In any case, a trip to a gynecologist or domestic doctor is the best action.
