Need other opinions

Ashley • Wife. Boy Mom 08/19/13. Angel babes 08/2012 and 03/2018. TTC #2
So the first picture I took and didn't see anything and about 2 hours later I wanted to look at it and it had a positive line! Then I took the 2nd one and it has nothing right now. Would it show a positive line just from sitting for awhile or can the positive take this long sometimes?! Help!! I'm going to be a week late tomorrow. Been TTC for 11 months
