VVVFL + Negative Tests

On Saturday morning I got a VVVFL on a pregnancy test from Amazon. Overcome with joy, I flushed the pee in my cup and ran to the store to get more tests. Since Saturday morning, I haven't gotten a positive result again. I've used the same brand, different brands, digital readers, etc. I have obviously tested in the morning but I've also tested at different hours. I'm 10dpo and 4 days until I'm supposed to get my period. What do you guys think, false positive, maybe? Or maybe there isn't actually a VVVFL?

Also, would you guys tell your husbands yet or wait for multiple positive tests? I struggle with infertility and I've had a miscarriage. I don't want to get his hopes up but it's so hard keeping it from him. I guess with every new negative it gets easier not to tell him.

Thank you in advance!

I've used the same brand and different brands. I've tested at the same time in the morning and all throughout the day.

I wanted to include the picture with a filter on it because you really can see a second line.
