Confused. Vvvfl bfp then bfn next day?

Question

Yesterday I took a test (frer rapid results) with fmu and had a line. It looked like a vvfl bfp. Today I took a test (same test) with fmu and its negative. I also took a wonfo test and negative. 
Any ideas why this would happen? Has it happened to anyone else and still be pregnant? 
Af isnt due till Friday but I'm not 100% on that. I think I should be 10-12 dpo. 
Any insight is greatly appreciated! Thank you!

Answer

Indent or chemical pregnancy if the line lightened/disappeared instead of darkened.

Answer

Do you have a picture of the Vfl? Maybe it was an indent, sorry 😞

Answer

I would test again in 2 days also even though you put them in the comment pregnancy tests are not allowed in this group that's why it's in the title of the group.

Answer

Took a rexall pregnancy test... faint positive. 
I can see it in person just fine even though it's still faint. No squinting. Took a frer with it but that test was negative. My lighting is terrible. Taken within time frame. Thoughts?

Answer

It was darker in person.

Answer

Wonfo. Fmu.
