I finally had my first ultrasound done today at what was supposed to be 10w2-3days. My LMP was 4/28/20. The tech told me I measure 9w2days but I ovulated May 13-15 so timelines don’t add up to me. Should I be concerned?? She wasn’t concerned and said that the doctor would just change my due date from 2/2/21 to 2/9/21 if she wanted to but they weren’t sure if she would. On a positive note the heart rate was 170 even tho they wouldn’t let me listen to it 😩
