No Period Symptoms....Strange

Ok, so I had sex at the beginning of September. My period is supposed to start in about 4 days. However, I don't have the usual sore breasts, attitude change, premenstrual cramps nothing. I'm sleepy alot, have had some serious body and face break outs, and I'm hungry alot with gas. My cervix was high instead of low, but it's still firm and slightly opened. Could that indicate pregnancy ? P.s. I normally have really bad break outs before my period
