No period, no positive.. help!

Al

I’m currently 5 days late and when I tested this AM there is still not an obvious line (I thought I have seen something extremely faint off and on since day of missed period).

I ovulated on Dec. 22nd and had what I assume to be implantation spotting on the 5th (some light spotting on TP only once)

Has anyone gotten a positive result this long after anticipated period and still had a viable pregnancy??

Starting to worry and get more confused every day.
