Red dots all over chest? Not itchy

I've got dozens of red dots all over my chest that are NOT itchy, they do not cause me absolutely any discomfort whatsoever, they're just there and really annoying. I do not believe it's PUPPS, I think it may be due to excessive blood flow or skin stretching, which apart from PUPPS, is the only 2 things forums and Google says it's could be. I have not gone to a doctor yet as it causes that little of a problem I forget to bring it up at any appointment but may do so at my next one. 
Any women expirience this ? I'm 29 weeks.
I will add a photo soon it is freeeeezingg and don't want to take my shirt off hahaha.
