No period, Pink discharge and bfn!?

Jessica
Hey. I really need people's points of view on this. 
So my period was due 2nd of Feb I had a few cramps few days before, nothing dramatic. Then on 3rd i started getting a very pale pink discharge. I thought it was just the beginning of a regular period to come an hour or so later but nothing happened. So prepared myself for a hard week and got over it. 
So I took a test on 10th and it was negative. 
The discharge stopped on the 11th. 
Anyone know what it could be? 
Should I count it as a period?
Help me please. 😞😫
