Did you get the February 13 due date early in the pregnancy from a doctor reading your ultrasound results?

Yes I was 6 weeks I'm kinda worried because now that I got bigger they are telling me I'm a week over then what I am

And they told me when I went for my 15 week ultrasound that I was 16 weeks but they said they didn't see the first ultra sound so they was going to keep my due date the same and that I was really 15 weeks I'm wondering why did the scan say 16

I been a week over sense I was 13 weeks

And on June 14 they told me they dI'd an ultrasound and say they didn't see a heartbeat and I was going to miss carry but on the 21 they told me I was 6 weeks 1 day pregnant and they say an ultrasound and gave me a due date of the 21 of feb.
