I am an 18 year old female. I'm not on any contraceptives because I don't have sex (I'm still a virgin). For the last, I'd say about a week I've noticed a muscusy secreshin with almost looks like it is bloody, yet it doesn't leave stains in my underwear. Also I had my period just at the beginning of this month so I can't be having it again.

Should I be too concerned about this? I've heard this happening to women on either the pill or the patch but I have neither.
