Period or pregnancy?

The last time I had sex was on the 14th and it was on one of those fertile days. My boyfriend and I used a condom, were afraid that it broke, but checked afterwards and it seemed completely fine. We had sex again with a condom that day, but we didn't see that it broke. About a week later I started to get symptoms for my period, but it didn't come when I thought it would (it can sometimes be irregular). Now, a week later and I'm still having all the symptoms (cramps, moodiness, acne, and my boobs are sore, but it hasn't come yet. Every time I've thought it came, it was only some cm discharge. My last period was on the first of October, and the one before that was on September 2nd.
