bartholin cyst?😥

i know this is really REALLY bad but i’ve had a cyst for years now and i’ve never had it checked out. it’s a little large but it hasn’t grown since i first noticed it. it’s soft to touch and painless, doesn’t really bother me at all. i’m pregnant now and have my first appointment to get a pap smear in a couple weeks. i’m nervous now that i’m finally going to get it checked out. i can’t find any information about bartholin cysts lasting for years. should i be worried that it’s cancer?😓
