Still spotting after 7 days

Ichigo • I have one daughter. I'm also pregnant with my second. Unmarried.
So as I may have mentioned earlier...I started AF early. A week ago. I was due to start yesterday. Gots Oregon symptoms yada yada. But even if I didn't have the symptoms....it's very abnormal to still be bleeding after 7 days. I only bleed for 5 on my normal periods. There's no pain..only had cramps and no smell. Any idea what could be happening.
