Hello I had my cycle June 20th it is always heavy and irregular due to PCOS. It stopped 4 days later. Then about 4 days ago I noticed a lot of pain with intercourse followed by bright red blood. That has happened every time I have had intercourse with my husband. I am 30 years old, 2 kids by c-section and my tubes cauterized 4 years ago. Today I felt for my cervix and noticed a hard knot on one side of my cervix (pencil head size) and I had blood on my finger after I checked and found this. I am also having dull pain in my lower back. Should I wait to see a gynecologist in 2 days or go to an urgent care clinic today? Do you have any ideas as to what this may be?
