Maroonish discharge. Are pretty good.

From last 5 days i got light brown spotting which later on converted into dark maroonish discharge in my pad. It is a kind of spotting plus liquidy discharge. It  usually happens when go for my morning routine(for pee and for stool pass). And then it happens in evening, not whole day. At the end of the day my pad has something spotting that's it. Nothing like periods heavy and fresh blood. I haven't do upt test because i thought my period has come. My last period was 25 sep 2020. It had perfect flow with 5 days long.  Please tell me what should i do.. i am worried because it never happened with me earlier. Also, please tell me is that my periods or something else. September is my 3rd month of trying for pregnancy. Earlier my periods are pretty good.
