9 week and confused about doc notes.

Kalina

I am nine weeks today and Doc tried to hear the heartbeat with a Doppler but couldn’t get it. Not surprising but still slightly worrisome. Had a MMC 2months ago, then one normal cycle, now pregnant again. Told me I definitely felt nine weeks pregnant. Then I noticed this in the notes… He didn’t mention anything about 11 weeks. What could this mean ?
