Please help 😫

well ive only had sex once which was in August. and two weeks later I got a normal bright red period no brown discharge. then in October i got light brown discharge for 4-5 days before my period actually started. and since I got it twice in October my second one was light and had four days of brown discharge with a little bit of fresh blood as well. so I counted that as my period. the second one started the 25th now November the app says I’m 10 days late. Yesterday I wiped brown discharge like once or twice I believe and now today nothing 😫
