Approximately 12-13 dpo...faintest of faint positive test

I took a pregnancy test and I see the faintest positive line. I'm not going to get too excited or take it as a positive yet because I don't want to get ahead of myself. It's so faint that it's almost to the am I just imagining the line. I really hope I turn out to be pregnant though. I feel super bloated today, tired (I feel really good from time to time and then suddenly it hits me like a ton of bricks that I'm exhausted), some backache while cleaning, diarrhea yesterday (which happened with baby #1), slightly queasy sometimes. For the most part I feel good though. I just don't feel how I normally would before my period. Prays that it's a baby! I am praying for you all too!
