I was the same . I went into my first ultrasound thinking I was 18 weeks 4 days, but she told me I'm actually 17 weeks 6 days. This was April 24th. We'll find out what we're having may 11th ❤️
I just came from my 20 week appt with my doctor and he said anything in a 2 week window either way is considered normal. Baby is measuring a week ahead for me.
Completely normal. Just go by the due date they give you and not by measurements. My little guy has measured ahead and behind and so have both of my girls. I always stick to the first due date no matter what!
