Hello. I am due for my period on 12/22 and typically I have a 35 day cycle. Last month I was 6 days late. Last Wednesday I started spotting brown and pink. As of today it has not been much. No show on my pantyliner, very light when I wipe. But as of yesterday I have cramping and pain on the left lower side of my stomach and it is slightly swollen. DH and I are not actively TTC but it is a possibility. I am leaning towards thinking this could possibily a cyst. My family does have a history and when I was a teenager I had one removed from my breast. Any thoughts would be greatly appreciated!

Thank you
