I agree with the other posters that, to be on the safe side, you might do well to cut it.
That said, perhaps cutting it would be easier if you knew you could do a little good for the world at the same time? It sounds to me as though your hair might be long enough to donate to Locks of Love.
My friends have done this (I can't because I dye my hair) and they've all felt great afterward.

From the Locks of Love website:
We accept 10" minimum hair length (tip to tip). We cannot accept wigs, falls, or synthetic hair.
Please bundle hair in ponytail or braid.
Hair needs to be clean, dry, placed in a plastic bag, then padded envelope.
We need hair from men and women, young and old, all colors and races.
[BOLD]Hair may be colored or permed, but not bleached or chemically damaged (if unsure, ask your stylist). [/BOLD]
Hair swept off the floor is not usable.
Hair cut years ago is usable if it has been stored in a ponytail or braid.
Hair that is short, gray, or unsuitable for children will be separated from the ponytails and sold at fair market value to offset the cost of manufacturing.
You may pull curly hair straight to measure the minimum 10".
The majority of all hair donated comes from children who wish to help other children.
Layered hair may be divided into multiple ponytails for donation.
Please note: Anyone can cut your hair as long as the above guidelines are followed.
Ready to put your money where your mouth is?? LOL
