Symptoms

Jessica
What are the earliest symptoms of pregnancy? And other "tell tell" signs? I've heard that your dog's behavior could change because they sense the hormone Change so they are more cuddly. What else?
UPDATE: so I had unprotected sex on my 14th cycle day, and it's currently my 30th cycle day. I was supposed to get my period 2 days ago and I know that doesn't seem like a long time but I am usually early.
