Red, pin sized dots on face, chest and neck WTF?!

GilletteBaby

Around 16 weeks I noticed some flat, pin-sized red marks on my chest and then overnight it seemed like more appeared on my face. My OB said its prob just the pregnancy but she tested me for low platelet count just in case and things seem fine. Tonight, I noticed a cluster of them developed on my neck, kinda looks like a hickey. Anyone else experience anything like this? OB says they are just broken blood vessels but dr google has me thinking they are something called petechiae and it's making me nervous!!! Anyone?!
