Pregnant?

Ok so I had a period at the very end of October that went two days into November. I had light spotting for a week then had another period after. I haven't started my period this month yet. I don't know if I'm late or early cause not sure when to base that off of. I have had signs like the sore/swollen breasts, fatigue, nausea, randomly going from constipated to diarrhea and bloating. I've taken a test last week that was negative. So I'm not sure. We do have unprotected sex frequently. Thanks for any advice in advance!
