Hello all and Congrats on your pregnancies. I had an ultrasound done at 6 weeks 2 days which should be very accurate dating wise because I had my lh surge tested VIA blood. We saw the slit flicker of a heartbeat but too early to measure and baby as measuring between 6 weeks and 6 weeks 1 day, is this normal to be behind a few days and is it normal to not be able to get a heartrate yet at this agr? I go back next week for another ultrasound.
