What cha think?

@ 10 DPO I woke up with cramps off & on all day (had me thinking AF was coming early. That afternoon I had spotting into that night I had spotting. The spotting was only on the toilet paper after peeing. Went to bed next morning it was all gone. No cramps nothing. Today @ 12 DPO temps dropped a bit. AF is due Tuesday. Should I prepare for her? I took a test with FMU it was a BFN - definitely sad bc I thought the spotting was implantation. Do you think there’s hope still? Below are photos
