Advice?!

So I had been on birth control for a few years and at the beginning of may I decided to get off of it because it was just too much of a hastle. I got my period immediately after the last pill...normal period lasted 5 days...husband and I had sex and what not and I used spermicide...now until this day I have not gotten my period..and I know sometimes it's kinda irregular after birth control but I figured since I got it right after it might be kind of on track...anywho this week I began having cramps, sore breasts, Clear white discharge (sometimes a lot) and rarely some light red/brown staining, bloating and some dizziness...but no period. I took a pregnancy test 2 weeks ago and it was negative...is it possible I'm pregnant? Please advice...I'm confused.
