Evap?

[Baker2937]

that’s an evap isn’t it? Period is 1 day late, no signs of it coming. Has been a strict 28 day cycle for about 6 months and has never been late in that time. 🫣

I think so. There’s a void in the middle of the line.

Sorry looks like an evap to me, these CB tests are terrible for it. If your period is late I would expect a strong line. Try a pink dye test x
