Guys I need your help

So my fiance and I are trying not to tell anyone (last night we told his friend) because we want to make sure everything goes okay and we see baby on the ultrasound (which wont be until 10 weeks and I'm 4 weeks 6 days now). We've had 3 previous losses and my family and friends know that.

So where I'm getting is that this friend of mine said that they want to right away after my fiance would find out/if I wouldnt theyd stop talking/being friends with me. I get anxious thinking about but at the same time I shouldnt have to worry about that. My other friend is understanding as to why I wouldnt wanna say anything right away. I already know what's gonna happen b/c I'm not saying anything for awhile.
