Do you have a picture of the 11 dpo test??

I had a faint positive on 9 dpo and then couldn't get anything on 10, 11, or 12 dpo with store bought.

But mine ended up being a chemical pregnancy

if you dind't use the same brand it is possible that the one you used at 13 dpo had a lower sensitivity in detecting de hgc levels, and the first one had a high.
try using the same brand or taking a blod test to be sure

I had the same thing - obvious faint positive at 8dpo with Frer (the only brand I use), now on 12dpo, have been testing every single day and they are all bfn - it's so disappointing, especially as I suffered a miscarriage 5 months ago.
Not sure if it's a chemical pregnancy or a bad test - no sign of af yet. Wish I knew what was going on!!

Sounds like what happened to me. I got a positive 3 days later went to the doctor and it was negative. I had a chemical pregnancy then AF didn't arise until 12 days after that.
