Prayers please!

Just went in for my first appointment. Should be 8 weeks 6 days. Ultrasound measured 7 weeks with no heartbeat. I'm devastated, as I just went through a missed miscarriage at 8 weeks in December. I go back next week to check for any progress but was told to not hold out hope. I know miracles can happen, but a two week difference when I'm sure on my dates seems like too far a stretch. Haven't had any spotting or cramping whatsoever. Have actually had morning sickness which I never did for my 15 month old. I feel like lightning has struck me twice. And in a row, at that. I'm thankful for any and all prayers. Thank you ladies!!
