Congrats! I got my BFP at 9DPO. I tested with a dollar store test and their was a faint line. I then immediately tested with a digital and it popped up as "pregnant"!! So a line is a line and you're pregnant!!
(For the dollar store test you have to pee in to a cup and then use a dropper so I used the same urine from that cup for my digital. If I didn't my digital probably wouldn't have come back positive until the next morning's urine).
My first pregancy was a super super faint line. I think my husband and I stared at it for hours. Then I wasn't sure if my mind was playing tricks on me so I tested everyday after that and it got darker and darker everyday.
