What is happening?!?!??!

Febbie

Went to the mall yesterday and i felt something came out of me, i thought it was af but turned out to be a milky white discharge on my underwear (tmi, sorry) after a few hours there was a streak of brown blood but only a small amount. Today is cd27 for me, this app tells me af will due today, the other apps 3/13.

Had like pinching feelings in mu lower and both sides of my abdomen, tested from 8dpo till yesterday 12dpo bfn. Haven't tested today yet, i'm waiting for af to show but hoping it won't.

Any ideas what happened yesterday? Thanks ladies!
