Discharge

So the last time I had my period was the 17th of October and after I got off I had unprotected sex like 3 times but he pulled out. Now I was supposed to get it today and I have no symptoms yet only a little bit of bloating. However, I have been discharging a lot and the texture changed from creamy to egg white yesterday (don't know if that matters). And my boobs have been a little sore. Am I overthinking things or can I be pregnant?
