Is it normal to be measuring 5 weeks on ultrasound when I should be 7 weeks based on my LMP? Concerned about previous miscarriage.

Question

I had a miscarriage at 5 weeks before, with a lot of cramping. This time, I'm not experiencing any cramping. Is it normal to measure 5 weeks on ultrasound when I should be 7 weeks based on my last menstrual period? I'm worried about another miscarriage happening again.

Answer 1

Are you bleeding? They way my doctor explained to me is it takes 2 weeks to conceive, and then another 2 weeks at least to show up. You probably didn't get pregnant until 2 weeks later than you lmp. Also, sometimes miscarriages can throw the cycle off as well. You said you lost the baby before, and I believe you know your body better than anyone. If you feel something isn't right, got to your OB. I believe as long as there is no heavy blood flow along with heavy painful cramping, you are probably ok. Not a doctor, but I am having my second child. 

Answer 2

Same incident happens with me. Iam 7weeks 2day pregnant.according to LMP. But ultrasound says it is 5 week 2days. And there is a sack.but nothing visible into it.plz give reply.is there any hope.or it is too early to say.

Answer 3

I would wait it out. Maybe go by the ultra sound. 

Answer 4

I had a scan and was around 5 weeks and was scared as only showed and empty sac I'm now 25 weeks so try not to worry I no its easier said than done

Answer 5

You may just not Have a high enough HCG to show baby yet. I know it is extremely stressful. It's very early for them to try to date your pregnancy. If there is no cramping and no bleeding then try not to worry.

Answer 6

Always go by first day of last period Ultrasounds can be wrong as many women found out after baby is born

I had mri with my first child and it was 4 weeks out As a result, my daughter was over 5 weeks premature and she spent 3 weeks of her life in neonatal 

Having my 2nd child now with no scans of any type We learned
