Pcos, pregnant or something else?

I like to get straight to the point: I had unprotected sex twice about 2 and a half weeks ago both times were on fertile days. Also my guy didn't pull out like he normally would for some reason. My period is late ( is not normal for my cycle) This will be day 4 if it doesn't come today. I know it's too ealry to test but is it possible that I have pcos unknowingly or am i possibly pregnant? (I know it sounds dumb but I've heard of pcos and im not very familiar with it and i heard the symptoms can be similar to pregnancy) im not over weight but any female can get it...
