I saw a Dr today and she was concerned since I have such irregular periods so wanted me to have an ultrasound to determine how far along I am.
I managed to get in this afternoon and the ultrasound only showed the sac, and the lady estimated around 4 weeks, 5 days.

Does this mean I say I am 4 weeks pregnant or 6 weeks pregnant? I get confused when a lot of sites count from the last period, so one site for example would say I am at 6 weeks now, not 4 weeks. I cant go off my last period though as it was 9 weeks ago!

You're 4 weeks.
