How many weeks am i ?

Cristian

So based off my LMP which was December 20th I know I'm 10 weeks pregnant. Yesterday I went to the doctor for a follow up and one of the nurses said on my files it stated I was 9 weeks bt she said on the ultrasound machine it said 11 weeks and my doctor measured my baby at 9 weeks and 3 days . I'm so confused and I forgot to ask my doctor cuz I was just too excited that I saw my baby. So how many weeks am I ?

I have a 32 day cycle if that helps 🤷
