Hi,
The red/brown discharge could be the start of your period, it's usually just the old blood cleaning out of the body. If you don't start your full blown period soon, you may want to take another hpt, or go to the doctor's for a blood test. That's about all you can do for now. Good luck and let us know what happens.
Well I'm Going to get a pregnancy test later so I'll keep you updated!:) but thanks
