I had my first scan today. According to my LMP I would be 7wks 2 days but my doctor is showing 5wks 2 days according to size. I ovulated around 14-15 days after my LMP. My doctor says I either ovulated late or something maybe wrong. Wouldn't it make sense that I would show shorter due to when I ovulated? This is my first pregnancy so I need some help understanding so I don't panic!
