Feeling frustrated

I’ve been pretty relaxed this cycle- until now. Glow predicts my period to start in about two days (my cycle length varies so I use it as an estimate). At about 9-10 DPO I had a bit of brown spotting, the following day I had quite a bit- some was even red when I wiped. I felt disappointed and assumed AF was coming.

Even though the spotting slowed down by the evening, I went to bed with a pad - and it was totally clean this am. The spotting hasn’t come back yet, just a very dull cramping.

Trying to be patient but it’s been a very up and down couple of days!
