It's just my thought on the subject but maybe Bp does not allow Pregnant Providers mentioning they are carrying a fetus due to that minor child being advertise as well within her ad or pics if posted. I'm well aware that you can't visually see the child but being able to see the very Pregnant Providers anatomy may be the issue and Bp may consider a minor being advertise as well.
Sorry, didn't look how old the thread was honestly just searched the threads that had to do with pregnant providers, I'm not very active in the hobby and hobby rules, I only post ads and read the threads dont really post but I apologize
