3 positives and 3 negatives... HELP!!!!

Soooo I don’t know what to believe any more!!! I have taken 6 tests over the past 8 days. All of my pink dye tests have been positive (☺️) but then the blue dye tests have been negative????? Anyone else ever experience something like this? The other two blue dye tests were take 11/12 at around 10 pm and then I took a digital one the morning of 11/16. The one in the picture I took today with the second urine this morning. I feel like the blue test in the picture has a faint line but I also thing I’m just grabbing for straws at this point 😒😒😒... my cousin is an ultrasound tech and scanned me yesterday (no baby yet). She is going to scan me again on December 2nd (that should put me at the 5-6 week mark!) Any and all stories and advice would be helpful... I’m still hopeful this is it, but I want to be prepared either way.
