Could it be ???

Brittany
So I'm one day late on my period. I have very sore boobs, dizziness at times, I can't even stay awake past 9:30 anymore, & for some reason I have chills. Could I really be pregnant?? When should I take the test? I don't want to be disappointed. I have been trying to conceive since I lost my last baby about 3 years ago.. I need advice.
