For the cervix checkers

Last year I had a miscarriage at 18 weeks. Prior to the pregnancy, I’d usually have a pimple like bump on my cervix that comes and go, and usually at the same place. I also have a normal pap as well. After the miscarriage I didn’t have it for 9 straight months up til recently. I checked my cervix yesterday and found that familiar bump in the exact same place. I found another bump at the opening of the cervix. I was wondering if this should concern me? What is it? Any feedbacks is appreciated!
