Suggest Treatment For Lump In My Labia Majora

Hi I was in the shower and noticed while washing a fluid like lump deep under the right side of my labia majora, it doesn't like a bartholin cyst (spelling?), it doesn't hurt and I can barley notice it. It doesn't make my out right lip swell or anything it is just a fluid like lump underneath all the tissue, when I press on it it seems like fluid and can be pushed around the area a little bit. I don't know what this can be. Any ideas?
