Trying not to get excited

Still have a week before my period is supposed to show up, but I have little signs that we might have been successful this month- exhaustion to the point of randomly falling asleep, frequent need to pee, discharge different than my usual premenstrual, craving relish, and bloating. None of which are usual premenstrual symptoms for me. Plus my dog who isn't usually very cuddly came up and lay her head and front paws across my uterine area and slept there for about half an hour and has been much clingier the past three days. I'm trying not to get my hopes up because I don't want to be crushed if my period comes, but we want a baby so badly...
