Finally announcing and nervous

So we are finally at 17 and a half weeks sending out announcements for what will be our first baby to our extended family and close friends, parents have known since 8wks, waiting for gender for social media. Somehow it makes me more nervous of something going wrong since more people will know. We have heard a heartbeat in the 150s a few times now but I haven't felt movement (at least that I have been sure was movement) we have our ultrasound on the 27th and I am excited but a little anxious since we didn't have any other screening done that there will be something wrong we didn't know about. I am overly nervous I think because we had a miscarriage in may and now every little thing makes me worry and it drives my husband crazy. I feel like I will feel better after the ultrasound where we actually see that the baby is there and OK and we will be halfway through. Anyone else have similar experience?
