Are ultrasounds pretty accurate now a days? I’m stressing out and i need to know. I went to my first ultrasound and they said they couldn’t see anything but my hcg level was 518. That was on November 5th. Then i went to my next ultrasound they said i was only 7 weeks wth a due date of July 14. Then i went to another ultrasound and she measured the baby at 10 weeks with a due date of July 13. Then finally i have been having slight bleeding and hyperemisis with this pregnancy so i went to the hospital this past Friday and the baby was measuring 6.6 mm. So 2.6 cm and i was 13 weeks. Is that accurate? Because I’m in a pickle!
