Pregnancy?!

Hi ladies, I am currently 18 years old and I am in a sexuall active relationship with my partner of almost 2 years.

I am 30 days into my cycle and still no sign of AF. My regular cycle is 30 days. I have had symptoms, however they seem to be a little different to normal. Every month a few days before I find I have sore boobs normally everywhere and get increasingly worse as my period is due. However this month, I have been suffering from sore boobs all over, my nippers seem to be a lot bigger than normal, and my veins seem to be more prominent them normal. I have also found that for the past 3 days I have felt nauseous. I haven't actually been sick yet. I have also been suffering from a stiffly nose, so I might just be ill, however I have also been suffering from headaches, especially on the left side of my face.

Another point to add is my cervical mucus. This month I seem a lot wetter down there (sorry tmi) but other months I am extremely sticky and creamy, and there is normally a lot!

Do these sound like pregnancy symptoms to you, or is it just my imagination. I don't want to take a test yet as I want to see if my AF arrives

Thank you
