Help!

I was supposed to get my period 4 days ago, I had light pink discharge but then had sex. And no bleeding at all now it's day 5. I have had all the symptoms of my period just no blood? Is that normal?? Also have had white discharge. Took a test and it said negative. I'm just confused of what is going on. I also stopped birth control 2 months ago after 4 years in it.
