Had an early reassurance scan today. According to my LMP (03/09/21) I should be around 7 weeks today. I hit peak ovulation 13/09/21- so ovulated early that cycle. First positive was 23/09/21 Today I went, I’m definitely pregnant, there’s definitely a sac, definitely one baby in there but is measuring very small (I didn’t get any sizes) I couldn’t personally see it on the screen. Unable to find a heartbeat due to size, have go back 2 weeks time. Absolutely devastated I can’t work out why the baby is so small, my dates are 100% accurate as I’ve been keeping track. I’m just so worried something is wrong. No cramping no spotting or bleeding. Is it normal to be so small?? I’m beside myself. theyve said not to worry but that’s exactly what I’m doing!
