My bosses 🙈🙈😜😜

I have 2 bosses, the first one was working for them full time before but they are old now just a part time job for them, then my other one working full-time, and they are friends like they are coming from England so how can I tell them that I am pregnant bcz if I tell one is going to tell others for sure am scared the sec one they don't know that am married, the old one they are like parents to me they know everything about me but the time I was seeing my and talking about marriage stuff I ask his blessing and we were already announcing to our family that we are getting married, now that he said it's still early for marriage he will bless me on time goes by. How do I tell them both that am pregnant and am 17 weeks 1 day my bump is big am try to squeeze my bump when am around them but its not easy at all 🙄🙄😳
