Cycle buddy?? Also, no period yet and still no BFP🤔

Jessie

So I was due to get my period Nov 15th... still no AF as of today. I took 3 tests over the last week and they were all negative. A few days ago I noticed slight brownish discharge but only when I wiped for about two days. When should I test next? Hate getting the negatives but where’s my period?! Lol My cycles have always been a normal 28-30 days whether I’m on or off birth control. Any cycle buddies having the same experience??
