Going to this grief conference at my church...

Alyssa
So I'm attending this grief conference at my church in a few weeks. My husband and I experienced our 1st pregnancy/1st miscarriage on Halloween night and I've been healing and doing better, but there are small things through out my day that bring me back to that sadness and I'm hoping that I can pull something from going to this conference and just relating and chatting to other mothers who have lost as well.
We have started to move forward and have started TTC again and I'm actually not quite sure yet what I will do when I find out the good news that I am pregnant again. They say it's not AS likely to have 2 miscarriages in a row but I thought I would never be that person with the unlucky fortune to have a miscarriage in the first place, so maybe I won't be lucky the second time around and that quite frankly terrifies me! However, if and when we get the BFP test, I'm not sure whether or not I should announce early. I told my work and close friends and family pretty soon after I found out the first time because we were just so excited but I figured it would be ok because I kept it off social media. To reverse all of the news we had just shared was awful but I did have support but the second time around, I am leaning towards keeping from everyone until 12 weeks (except my boss). I'm afraid if I tell people even that are in my close circle early that I'll miscarry early again :( almost that karma or something!
Anyone that has been in this position, please tell me you were having all these confusing thoughts run back and forth!!
