When was the lastest Positive home pregnancy result you've had?

So I know that it is possible to get a positive result late, my little sister was about 3 months pregnant before getting a positive home pregnancy and blood test. My last "period" if you can even call it that, was very light. It was only existent when I wiped I never had to use a pad even for bedtime. It only lasted 3 days where usually it lasts 5-7 days for me. I still have been super bloated lately which only happens to me before AF and then afterwards the bloating goes away. I've been getting headaches alomost daily, which has only happened to me when I'm taking letrozole which I skipped this month until I know for sure. I just feel different this time around. Today I would be 5 weeks and 6 days if I am pregnant but this morning's test came back negative. Has anyone here gotten a positive after 6 weeks and how far along were you when you got your positive? Thank you in advance.

P.S.-As a side note please don't tell me that it's rare to get a positive result late cuz I know a lot of women that got a very late positive, and you can find them all over on google. It's not as rare as people think.
