Ok, so my girlfriend's period is late. She says it's pretty random... usually between the 7th and the 15th. Well the 15th is past and still no period... I'm fairly confident that she's not pregnant, but I guess I'm not 100% sure... so I guess you could say I'm a little worried.

Anyway, my question is... is it normal to have a late period?

and... how long should I wait before buying a pregnancy test?

Thanks.
