I need a miracle...

Anyone ever have this happen to them....I’m pregnant with my 🌈 baby according to blood work I should be 7 weeks today. I had a transvaginal OS last Friday at 6 weeks they only saw the yolk sac Doctor thought maybe I wasn’t as far along as the blood work confirmed. Went back today for another OS 7 weeks and they still only saw the yolk sac and not much growth from last week. The doctor thinks it could possibly be the start of a early miscarriage 😭😭. I don’t have any bleeding or cramping. My boobs are sore af, I’m exhausted, moody and I’ve been peeing like crazy. This is baby#2 and I’m already starting to show. Like I said they want me to come back next week to check to see if I have any growth before doing a D&C or put me on the medication. Please tell me someone has had this happened and a miraculous miracle happened and you have a healthy baby or are still pregnant?? Trying so hard to stay positive right now. 🌈😭🙏🏻
