Based on LMP I should’ve been around 10 weeks when I had my first US, but measured 6w2days. Everything looked good but no heartbeat. A follow up US this week to look for growth/heartbeat. They said it’s usually around 6w4days for a heartbeat. HCGs were ordered in the waiting period, first was 26,578 and 48 hrs later was 25,695. I’m very concerned and having a hard time holding onto hope. Advice?
