10 days late, negative HPT

Le

I took an HPT on CD 30 and it was negative. Aren't they 99% accurate by that point?

Here we are on CD 37 and still no sign of AF. This has never happened. My cycle is like clockwork, every 26 days.

Oddly, the one thing I am seeing is EWCM on random days... so much that I kept thinking it was AF. Could I have spontaneously started peri-menopause all of a sudden 😕
