Help please??

I have been experiencing lots of creamy discharge recently, been fighting exhaustion, etc. Anyway I had sex 2 times, on the 20 and 21 of December (ovulated the 23).

My period was supposed to start yesterday but this morning I had random pink spotting and it has turned to dull brown discharge and its super light. I've had no cramping. Anyone have any idea what's going on?
