Confused 😑

Ok so I'm currently breastfeeding my 9 month old but I've had my cycle back since she was about 4 months. My husband notice things and said "i think you're pregnant" which is weird because hes NEVER been able to tell... but I noticed things "off" as well. We were both convinced. Now I'm 3 days late for my period.. I usually use a pink dye but my husband forgot and got blue. I took it this morning and this line showed up within a minute or so and the pic was taken in the time frame. I know blue dye tests are horrible with false positives but I always thought they were thinner or miss placed or even grey 🤦🏼‍♀️ has anyone gotten a line that looked exactly like a faint positive within time frame and it be faulty?!
