Thanks all :( I did have a super faintline throughout the day yesterday and then a BARELY darker one today which I'm attaching, and is pink. But the temp dip and how faint the lines are means impending chemical in my experience...
I'm attaching both charts, as depending on setting I'm either 10DPO or 12DPO. I DO think 10 is more accurate since my cycles are so consistently 30-31.
