Lots of preg symptoms... but neg test... am i pregnant?

I had dec 20th-Jan 10th. My last period was on Dec 26th. I had a normal 5 day period. I was going to be expecting my period last saturday, which was Jan 23rd. The period never came, but I had cramps off and on all day. I first started getting a lot of l discharge. After that i started getting very tired and headaches. I was also starting to get light headed and woozy. Then the 26th came of this month and i had some spotting, it was pink and brown discharge. I had some more spotting today so i thought i was starting but the period never came. I never spot or cramp unless im starting my period. Im only 20 yrs old, when i get my period i just flat out bleed. No beating around the bush i guess you could say. I took a preg test this morning and it was neg. Am i pregnant?
