preggers or not??

so lately I've been the following;

short of breath

constipated

itchy nipple

dizzy

mild nausea (lasts hours but no vomiting)

random lower back pain (not always)

headaches

moody

not really in the mood to eat

discharge (water.. occasionally cream.. and eggwhite)

frequent urinating (to the point where I'm waking up in the middle of the night)

my period is due in a week and it's too early to take a test.... my husband and I have been TTC for over a year... could I be preggers??? anyone have the same symptoms and got good news that they were preggers?? please share your stories, I don't have family members to talk to about this. thank you!
