I had my period last month around the 17th. This month my period was to come around the 18th and I'm now five days late. I'm having some very light pinkish/clear watery discharge, cramping and lower back pain. My breasts are sore and today I feel a little nauseous. Could I be pregnant? Last month my period was kind of weird it came and was heavy only one day. But I did have sex (unprotected) last month the day and days before my period started. I haven't had sex since before my last period could I still be pregnant? I hope so.

A period can be late for many reasons. Since you're late, now is the time to test. Use first morning urine so the hormones are more concentrated and follow the directions carefully.
