Confused

At 11 DPO I took a pregnancy test first pee of the morning and got a faint positive test. 13 dpo (today) I didn't take a test until 4 pm and you can hardly see a line but I still feel like theirs a possible line. Is it possible the 11 DPO test was darker because it was first pee of the morning? I'm starting to get really mad/sad because I so badly want to be pregnant.
