Glow Switiched My Dates?!?

April • 28yo Married 8yo💍8yo DS🤸‍♂️ 5yo DD🤸‍♀️1yo DS (born asleep)👼 & 🤰 #4🌈

AF was due to show her ugly face 12/5. Of course I tested a couple of days before, the day before, and the day of and I got all BFN.

Glow asked did my AF start, so I said NO and BOMB! It switched my expected due date for AF to 12/7.

Like what the heck man? I had some brown spotting on 12/5 but that's about it. I kinda got excited because AF was late until it switched my dates. Now idk if it's still considered late or not. I've already used my last HPT which SUCKS by the way.

So I'm not buying or testing until at least a week has passed if AF is a No Show. Good HPT are not cheap and I re ally don't wanna keep wasting money on BFNs.

Is anyone else having this issue or is around the same cycle?
