Brown spotting while chest cold?

shauntiney 🌺
I have a chest cold, no meds refused toughing it out, all the while coughing up lung (expression) anywho i have been spotting brown old blood like breakthru past few days. I already had US 8w3d heart 160 spotting at that time also. I was told linning has blood but will dissipate absorb later. Just wondering if anyone had a severe cold that has brought on spotting?
