Dark brown at missed period?

Pixie

Hi all,

So this might be tmi but I’ve been having brown discharge the last three days (mostly when I wipe). I use this app and another to predict my period and have been using it for more than a year. According to the other app, I am four to five days late. According to glow I was suppose to glo I was suppose to have started it yesterday. Usually it happens right between, closer to the other app.

I took a hpt this am and it was negative. Today it’s been a little more of the brown discharge and my cramps are a bit more but they feel different than my regular period. It feels like a faint pain and lots of fullness which is slightly painful. I did have a weird headache for two days and today I was a having these slight dizzy spells.

Anyone have any idea with what could be happening? I’m so confused.
