Has anyone ever had a bartholins cyst??!

Hi!
I'm 31 weeks pregnant and the last two days I have had an intense pain down below, kind of in the fold between my leg and vagina.. I googled a lot of course and I am convinced it's a bartholins cyst! I'm just wondering if anyone else has had these and how you got rid of it? 
I had a smear test last week and have a doctors appointment this week coming so I will also ask then if this is still bad. It's so sore to sit or get up or walk and everything!
