Pregnancy Thing? -Maybe TMI

I found a few bumps on the inside of my labia minora. One side only. Two of them. Smaller than an eraser head. Obviously I've already called the doc but wondering if anyone has experienced this? I went through fertility stuff and have been tested and cleared for all STD's and like issues. The bumps are the same color as surrounding skin and don't hurt or itch. Any ideas?? 27w+4d
