tmi - cervix question- worried

[Lovn.sunshine]

So I was checking my cp [tracking for ttc] and found a rather large lump on my cerix.... right at the opening. I cant get a doctors appointment til next week and I'm terrified to ask dr. Google. Anyone know what it could be? Didn't have it last cycle. It's probably, by feel, at least the size of a grape and is hard.
I've got myself all worried now
