Someone spilled the beans ?

I found out today that someone I know through mutual friends, who is apparently on Glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a>, figured out my identity and proceeded to tell those mutual friends that I am pregnant. I'm only 6 weeks and most of my family doesn't even know, but now the cat is out of the bag!  I am so steamed.  What happened to etiquette and maintaining each other's anonymity on here?!  We should know better - come on, people!!
