Hello to all;

I really Don't want to waste a pregnancy test. Especially since its onle been 1 day.

I really need some advice.
I am 28 and healthy.
Heavy white discharge is not a normal thing for me, before or after a period.
Here's the situation: On October 14, my boyfriend had some type of mental lapse and did not pull out when he was done.
On October 21, I got my period, it was right on time and appeared to be normal.
My period was due yesterday 11/22 and nothing!
Today I have a heavy white discharge that has me running to the bathroom with a tampon almost every hour.
I work so much that I'm always tired. Last week, I had similar discharge, I figured I was ovulating.
this morning it was definitely, "mucousy" appeared white on black underwear, but when I wiped had a tint of yellow/brown. I thought my period was here and still nothing!

Could I be pregnant? Only other symptopm is irritability, unstable mood.

Please,

Please help!
