I'm 16 years old and on Friday 1/27/2012 I went to go use the bathroom when I wiped I found this clear jelly-like substance with blood on the paper. Again today 1/29/2012 the same thing happened but the color changed too a very light yellow still with blood. The blood isn't heavy it just looks like a little stream of it.
I've had sex with too guys one in March and the other in July or August of 2011. I do use tampons and my period is suppose to be coming down on the 8th of February.
Please Help Me I'm Really Scared and don't know what to do.

The yellow seems unusual to me. Is there a noticeable odor? Have you had sex recently?

It could be anything from normal fertile cervical fluid or something like a yeast infection or STD. You should consider making an appointment with your doctor.

Okay Sorry The Lighting In My Bathroom Isn't All That Good So It Seemed Yellow But Its Actually Clear.
There's An Odor But It's The Same Odor I've Had Before I Had Sex. The Last Time I Had Sex Was In July Or August Of 2011.
