Idk anymore lol

On the 11th of this month had that brownish pink discharge then for the rest of that week did t have anything else. Had intercourse on Sunday, Monday wiped and there was some brown and then very light pink, yesturday was barley anything, this morning I woke up and there was brown again…. So at this point I’m not sure what’s going on and by now I’m normally on my cycle.. yes I have irregular periods but I have always seen that bright red.. nothing like this… so at this point I’m not even sure I’m pregnant anymore 😞😞
