I hope it's normal, because i've just discovered them too!

They are called mongomery's tubersticles lol I think I spel that right :d

Are they common during early pregnancy?

The white bumps are common for everyone, whether you are pregnant or not. Some women say that their get larger when pregnant but it depends on the person.

If you think you are pregnant test.

I've been noticing them for a few months now and I was kinda freeked out glad i'm not the only one
