Pink CM?!

I’m 15 weeks today. I just went to the bathroom and wiped and there was light pink CM. i have no pain or cramping. I don’t want to say anything to anyone because it’s Father’s Day and my in laws are here and I don’t want to run anything. I am so scared. I’ve had two very early miscarriages. I just heard the babies heart beat yesterday and it was fine. Can some spotting be normal?
