I had the same thing and I'm now bye me 42 + weeks and bye the scan I'm 41+2days it happens as not everyone ovulated the same so that's where the confusion lies.
Same here i was measuring small so my due date changed from oct 6 to oct 13. Dr said sometimes we ovulate later in our cycle so it was nothing to worry about
Don't worry its normal...I m in my week 19, My due date moved to 19th Nov from 27th Nov after my last scan
Ah don't worry! I'm sure everything will be fine. I had the exact same thing happen to me in the beginning. I thought I was around 6.5 at first scan but baby barely measured 5 weeks. When I went back for another scan at around 11 weeks the growth had gone right back to where I'd originally thought I was at! So I was almost 13 not 11!
Yup, I had the same thing. They did see the baby and the heartbeat she just showed smaller than what was calculated based of my LMP. My due date was pushed back 1 week (which is super depressing because i was supposed to be 10 weeks at the time and going backwards makes the pregnancy seem longer) BUT we are now 36 almost 37 weeks and she is now measuring 2 weeks ahead!
