Bruises showing up everywhere

Aubrey • 25, married to the love of my life, our baby girl was born 9/17/17 ☺️❤️
They are small but over the last couple days I've noticed about 10 bruises that just popped up out of nowhere. I don't do any contact sports, my workouts consist of plyo's and running, and I don't recall bumping into anything? Any ideas why this could be happening? I'm 21 years old and I'm pretty healthy minus a cold I've had a rough time getting over recently.
