I got a positive pregnant test on January 27. I went in for my first appointment on feb.12 and the ultrasound tech told me I was less than 6 weeks but wouldn’t give me an exact date. I went in again on February 25th and according to me LMP I would’ve been 8 w 4 days. The doctor told me I’m measuring 6w 4 days. I’m soo scared of miscarrying but my doc says I probably got my LMP mixed up which I charred so I know I got it right . 5 years ago I had miscarriage it was at 6 weeks 5 days. I went in for my 8 week scan and the baby was only measuring 6 weeks 5 days. I’m so scared. Has this ever happened to anyone?
