Grain of rice size lump thing up my fanjo

Just found by chance. I don't have any symptoms, but I was searching for my cervix a few weeks ago, because I've just never had the urge to venture down below before so was having a random poke about.

About 3 inches inside on the right side of my vag wall is this lump, it's like a small grain of rice that's hard but sorta moves a bit if you push around it. Could have been there years it was just found by chance. I can't tell if it's growing out of the wall or from under it. 

Any google search just brings up cervical stuff but this is my vag wall not cervix. I'm 35 and have kids, I don't really know what I'm asking, has anyone had this? 

Its not sore it's just chilling there by itself  causing me some worry. I have an appointment on Monday but you know what it's like, it's dragging. My husband says stop looking online, don't look on Google, just think of something else, but I just can't. 

Thanks!
