I am pregnant with my second child. Durring pregnancy of my first child I noticed some bumps that weren't really blister-like. They were soft and completely painless. They last about 4 months then disappeared. I am now pregnant again and notice the same effect. It is small like a zit but painless. It is not hard like a wart. I had been tested for stds including Herpes and Genital Warts prior to becoming pregnant in which my results were negative. What the heck can it be and why is it that I only notice this seeminly during pregnancy?
