Blue Dye Test! I KNOOOWWW

I’ve taken 3 blue dye test all with faint positives in the time from 3 minutes or less and I can see the line. But the two Walmart cheapies I’ve taken. I don’t think I see anything 😩 idk dpo. I wasn’t necessarily trying. I had a miscarriage 5 years ago and then again 3 years ago so I honestly just thought maybe I couldn’t/wouldn’t get pregnant again. Not that I’m complaining if I am. It’s actually kinda got my hopes up. But however; I’m not sure what to think haha. I’m going to the health department tomorrow for a urine test as I currently do not have insurance. But anyways just any advice, or anything would be nice. TIA ❤️
