do I take the test?

Alright. Please no judgement. Just looking for insight. 
I had sex about a month ago and it was the last day of my period so I wasn't so much bleeding as I was just discharging that last little bit. 
However. The sex did make the bleedingjnf start again. So he decided it was okay to just cum in me like an idiot. 
We got the day after pill. 
But my period is now late. 4-5 days. 
Also no early signs of pregnany. Just some random acne.
Do I test, or wait?
