Two faint lines then a negative 😧

BabyBoyMama

πŸ‘‹πŸΎ I got two faint lines. First on 11 DPO (picture 1 with green)

and the second on 12 DPO (picture 2).

Both these tests were in the afternoon/night. Today (13 DPO), I retested with first urine and got a a negative.

Any ideas what’s up? Here’s my BBT as well.
