Am I Pregnant or Ovulating? Please Answer!

So my last period was on April 4th it last around 4 days, ever since my period has stopped I've been craving cheesecake really bad to the point we traveled to every store just to get one and ended up eating it all LOL! Monday night I went to the bathroom, I realized I was spotting I had some spots of red blood and when I wiped it was brown. I also started to have sort of a pinching feeling in my ovaries. My boobs have been somewhat sensitive and have moments where they start to hurt. On Tuesday my SO noticed they were slightly bigger, I've been bloated and have some moments where I feel sick. I've had some lower back pain but not to bad, I've had a somewhat bigger appetite and I've been really tired. I checked my cervix and they were high open and between soft and hard, not really sure of the texture... I've had clear watery cm as well. Any clue of what's going on? Im ttc for my first baby and have been trying since September since I got my birth control out..
