Anyone get a BFP after 16 dpo??

Lindsey • IVF miracle born 12/11/2018, surprise baby #2 due August 2021!
AF is a day late, sporadic brown spotting for 3 days, watery cm. I had what I assumed to be implantion spotting at 7 and 10 dpo, spiked a fever of 100.2 the morning before AF was due, and yet I'm still getting stark white bfns. Would love to hear some stories of bfps after 16 dpo to give me some hope and help me pass the time before I figure out my fate this cycle.  Thanks girls. 😊
