second opinion?

I had a small bump on my vagina and I went to the gyno in which she said it's a pimple. It's gotten smaller but it's still there. However, while showering I know felt another small bump. It's on the top right where the curve is. I did he tested for STDs and everything came back negative. I'm currently on my period and it just making me nervous. Should I go to a new gyno or should I wait it out?
