TMI description.

So last night for whatever reason, I was puking and really sick for four hours. I've had bouts of nausea/vomiting  this entire month of January. 
On one trip to the toilet, I had some brown tinged with pink discharge come out. Throughout the night I had more discharge but it was clear. I'm due to start AF in three days. 
Is pregnancy a hopeful Possibility maybe??? I'm still queasy this morning.
