Symptoms was anyone else like this??

Jo
The last 2 weeks my cm is dry. Some people say they are really wet when they are pregnant, but I've been dry since my ovulation and I'm not normal like that. I've also been having  symptoms like, lower back pain, feeling nauseous in the morning, boobs feel bigger, headaches, little left side pelvic pain etc. 
my period is due tomorrow but it just feels different this time!? 
Was wondering if anyone else was the same??
