Not sure if I am pregnant, help please

Kendra

I had what I thought was a period on October 23-26 it was very light though (it was red and brownish) which was weird cause my period is usually heavy and lasts 7-8 days. Now today I have started to spot/bleed again. I took 2 pregnancy test last week but they both came back negative. I’m just confused and need someone’s opinion on what they think could be going on
