Im freaking out should i be letting myself get excited?!?!?!

Resa

So i when to the doctor's today to get a cold checked out and mentioned that i was a day late on AF and they had me pee in and cup and told me there was a faint line?!!!! I got blood work (which wont come back until tomorrow) but they wouldnt tell me that if it wasnt a really good chance of being true right?! Like a faint line means positive right???
