Normal.. or possibly pregnant?

I was bleeding then it stopped and then started again and I believed it was my period we bd 2 days after and I felt like I ovulated the next day but don’t know and the following day I spotted and now it’s been 7 days since I think I ovulated and I started spotting brown blood I don’t know what to think I’m wondering could I be pregnant? Or is this normal? Kinda freaked out how could it be my period when I just had one? Or is it suppose to be like this post pregnancy?
