Had a period last month and this month…..

This month I missed my period I’m assuming. I am unsure when ovulation was. I tested Monday 10/16 and it was nearly positive. Meaning I was declining in LH surge I’m sure. So maybe this past weekend? I was supposed to start my period 10/14 and did not. Now, today I’ve had brown discharge and cramping. No red AF. What could this mean???
