First Ultrasound No heartbeat

Jennifer
I was told that I was due December 24th based on LMP and that I'm 8w along, although I have been going off of my conception date, so had me at 6w and 5d. I bled on Sunday without any cramps so they bumped up my first OB appointment to yesterday, and the doc wanted to do a transvaginal ultrasound. This is our first child and it was exciting although I wish it were under different circumstances. 
Well, I saw my little peanut and they measured me at 6w 2d, so my calculations weren't far off! Lol. My EDD is now Januray 9th, which makes me happy. My family has 4 December birthdays (including mine) so I really didn't want to deliver on or around Christmas.
Anyway, I need your prayers. They couldn't find a heartbeat so I have to return next Tuesday for another ultrasound. The doc said it is still early to see it, but if there isn't one next week I will have miscarried. 😭 I am keeping the faith and trusting Jesus every step of the way. Please be praying with me if you pray. 🙏🏼💞
