doctor visit

My last doctor appt they told me I had just turned 6 weeks instead of the 8 they thought I was. Therefore no heartbeat could be found. Now they said my hormone levels are low and I might miscarry. My husband and I have been trying for a year and will be heartbroken. Our next ultrasound is on Friday. Anybody else go through this and not miscarry. Any advice or suggestions to handle this?
