I used to faint loads around my �time of the month� it something to do with lack of iron. It is scary but just make sure you turn her on her side so she doesn�t swallow her tongue until she comes round. It wasn�t ever scary for me just really embarrassing. I�ve landed on my teacher, Fainted in Argos and put in shop window on recliner to recover, fainted in Anne Franks House and in my local pub on the dance floor, which would have been all right if I hadn�t woken to my mate slapping me hard round the face :-) Just take her to docs for blood test, they will soon tell you what is wrong.
