Need prayers and encouragement

Today was my first appt, I’m supposed to be 8 weeks 4 days by my last period. Got my first positive test on April 17th, 3 days before my missed period and it was clear. Digital showed positive the next day. I have had extremely strong symptoms (strongest of all my pregnancies) and no problems spotting or cramping at all. My ultrasound today was not good, we could only see a yolk sac and was measuring 6 weeks 5 days. Dr is hopeful and said there’s a 50/50 chance right now. They drew blood and I have a repeat scan next Tuesday which he said will tell us for sure because by then there should absolutely be a baby with a heart beat. Has anyone been through this and everything ended up fine? I’m trying to stay positive but also don’t want to get my hopes up. We have tried almost a year for this baby. If you’re the praying kind PLEASE help us pray this everything will be fine!!
