Could I️ be pregnant?

Some TMI

My last period was 10/21 and before this cycle my cycles were anywhere from 34-40 days. This cycle was 42 days. I️ have no clue when I️ ovulated this month. My periods are normally really really heavy and I️ get extremely painful cramps. Well this cycle I️ went to the bathroom and saw spotting so I️ though I️ was just starting my period but was confused because I️ wasn’t cramping at all. This was 12/2. I️ figured it would just pick up and get heavier and already thought I️ was out this month because of all of my BFNs. Well now it’s 12/4 and there has barely been any blood at all and it’s just brown. My only other symptoms making me think that I️ could be pregnant would be nausea, bloating and soooo tired.
