Lumps on my cervix!! Help?

Hi ladies.. some advice please.. I'm a little concerned because I don't often check my cervix but I have just had a feel around and I have 2, maybe 3 hard lumps on my cervix! They were not there last month. Could these be polyps? Has anybody had these? Do they affect fertility? Do they disappear or do they have to be removed? I have not had any pain, no irregular bleeding etc.. thank you!!
