Q: Measuring slightly behind on early ultrasound scan should I be worried??

Hi ladies

I hope I don't sound crazy but I had an early ultrasound scan yesterday to monitor progress due to early bleeding at 5 weeks.

At 5 weeks they saw a gestation scan measuring 4 mm and HCG was over 1700.

Yesterday I had a repeat ultrasound measuring 7mm, we saw our tiny baby and the heartbeat!

They said I was measuring around 6 weeks 3 days. I know my LMP says I was 7 weeks 6 days yesterday which I know is wrong as I ovulated May 11th making me 7 weeks as of yesterday.

Should I be concerned the dates are 4 days out???!

Hi, on my early scan, I was 4 days out to my LMP. My doc wasn't concerned at all and said it was quite normal to be off a bit. I am now 13 weeks pregnant and everything is great :) Try not to stress, I know it's hard not too.

I went for a placement scan at 5w2d as I was having terrible left sided pain. We could only see the gestational sac and yolk sac measuring 5w5d and no sign of fetal pole or heartbeat at that time. That same day my HCG was over 13,000. The ER doctor told me it was likely a blighted ovum, but my RE said everything was perfectly fine. I went back to my RE's office at 7w5d and there was a baby and a heartbeat measuring at 7w3d, but my sac was only measuring at 7w. I asked my RE if there was reason to be concerned as we knew exactly when I ovulated and I got my positive test at 9dpo so we were confident I had implanted about 6/7dpo. She said they don't worry unless it's over 7 days behind and she released me to the OB that same day. When I went for my 13w scan at 12w6d I was back to measuring ahead. I will be 20w tomorrow and everything is going perfectly. Easier said than done, but try no to stress. Congrats and good luck!

I would not be concerned unless your Dr is. I am 21 weeks now and sometimes I measure on schedule and sometimes I'm a few days behind. My Dr's are not worried at all.
