my AF is due in like several days, I have 35-day cycles and I'm just freaking out about the possibility of pregnancy! I've been having nausea the past couple days, but I am one who easily gets nauseous anyway, and apparently pms could make you nauseous too, so I'm just FREAKING

I always use a condom when I have sex, but still, the scare is here...

Do any of you know any early telltale signs that are different from pms signs? Can you tell by cervix position?
