Possible miscarriage

Desirae

I had a 10 week ultrasound. From my end everything seemed great with the ultrasound. Doctor says my gestational sac is measuring at 7 weeks and baby at 9 weeks. Also says the yolk sac is mis-shaped which is also concerning. Heart rate was 193 which I did think was a little high but it has been 6.5 years since I had a baby so the fact that there was a heartbeat was all I needed to hear!! They have told me I have about a 99% chance of miscarriage. Took blood for hormone levels and they came back normal. Took it again 2 days later and there was a slight increase(and they still don’t sound too optimistic).... I have an appointment for a second opinion and haven’t changed a single thing I had been doing but just curious if maybe anyone had some insight????
