Please help.

I have a high chance of miscarriage so I am highly stressed.

Yesterday I had an us. My ob told me I was measuring 5 weeks exactly. According to my dates I am 5w5d.

She is quite blunt and not very reassuring. I asked her why it would be different and she said I probably got my dates wrong. As i chart I know it is unlikely. I was basically pushed out the office straigh away and didn't have time to ask any questions.

Does this variance matter?

It is so early. I went for an u/s at a normal bulk billing place when, by my dates, I was 7 weeks.

Embryo at that stage measured 6 weeks 1 day. I didn't like it, but there was a heartbeat so I tried to stay OK with it.

Shortly after at the OB, when I was 9 weeks by my calculation, her machine came up with 8 weeks 5 days.

By the time I got to the 12w ultrasound (which I had at 12w 6 days), the dates match.

Last pregnancy at 8 weeks the OBs ultrasound was almost 10 days behind what I calculated, even though there was a heartbeat.

I know its not really possible, but please try to stop worrying, its really early.

It must be very hard not to worry. I had a miscarriage a month and a half ago, so know I will stress next time around. US are variable, especially so early. Sending sticky thoughts your way.

The measurements are just an average, all babies grow differently. Hopefully it's nothing. original.gif

I would choose a different and more supportive OB if I were you.

My DD's last pregnancy by her dates was 6 weeks 1 day when she went for her first scan but there was nothing more than a yolk sac, she went back the next week and she had a 6 week 4 day embryo with a HB.
What happened in that time is hard to understand but apparently she grew 1 week and 4 days in just 6 days.
I am convinced that in the early days of implantation and growth there is a variation in how quickly they grow.
Please do not give up hope, lots of very good luck.

ETA--If this was done on a small scanner in the doctors office it is probably even less cause for concern.

Hi,

I know how stressful this can be and I send you big hugs.

My 2nd bub was like this. I knew my dates etc so when at the first ultrasound he was measuring only 5 weeks 3 days not the 6 weeks 2 days I had expected I was really upset. No baby could be seen just a rather odd shaped sac and I was told not to worry, however the lady who did the ultrasound was also abrupt and not very apprachable which made me feel worse.I got the report and it said probable miscarriage but as it was only early wait and see.

2 weeks later bub had picked up! Measuring a bit closer to dates and a heartbeat, he scared me at EVERY ultrasound with things not quite right etc but now he is a healthy 3 1/2 year old.

Ultrasounds are said to be about 4 days out either way so going by that your baby is still in range.

I hope you can get a positive ultrasound soon.

If it helps, my DD was conceived with IVF and my scan dates didn't match the very exact dates I had from fertiisation/transfer etc.

Thankyou so much for all your prompt replies. That is exactly what I needed to hear. (My DH is laughing telling me 'told you" as I kept him up half the night)

I know I need to stop worrying but finding it really hard.

When I had my US at 8 weeks, the technician told me I was measuring at 8w2d, "give or take 6 days".  So basically it the variance can be almost a week either way wink.gif

My OB told me bub was growing too slow, a millimetre smaller than he should have been at 8 weeks and I would probably be miscarrying. He's nearly 9 now. original.gif

A blood test would be helpful for you I think. Have you had one yet? It will give you a pretty good line of how things are going. They can usually get it done urgently so results are back by the next day.

At both my DS ultrasound and my current pregnancy (13 weeks) the ultrasound date was 6 days behind where I had dated. My DS grew into a very healthy boy even though the dates never ended up moving closer to my calculations. I tried not to think too much about it because I didn't want to worry. The technicians both times have told me that I must have had my dates wrong but for DS I certainly didnt (unless there is something very odd going on 'in there' that takes a week longer than normal!)

Good luck hun!

When I went in for my dating scan, I was supposed to be 7 weeks, but I turned out to be 6w 2d or 3d (I can't remember which). I was positive of the dates too as we'd only had sex the once, but who knows, the sperm may have not met the egg straight away? Then for the rest of my pregnancy, from 12 weeks onwards, DS was measuring ahead. The US tech couldn't do the NT scan because DS was too big! Good luck for the rest of your pregnancy, and as cliche as it is, try not to stress original.gif

I understand the stress about losing a little one, and am sending a hug your way.

Re the ultrasound I would definitely NOT be worrying at this early stage. I have had a lot of scans in my pregnancies due to another issue and have been told by every single scan technician to remember that the dates are just approximate, as they are only human and especially at that early stage if they are out by a fraction of a millimeter that can change your dates by a day or two. When you are in an OBs office and she is under the pump and doesn't have a lot of time to get the basic measurements it could be that she was just out a tiny bit and that explains it.

In my experience, an OB will be open with you if they see a reason to be worried about measurements. Last time my DD was measuring about 2 weeks out in her torso measurements which freaked me out, but the OB (specialist at the fetal medicine unit of the tertiary hospital) said that sometimes they are just about to hit a growth spurt so if they'd done the measurement three days later it all would have looked fine - and two weeks later all the measurements truly were matching up again.

Hope that helps, stay positive, and remember the OB would have told you if there was a concrete reason to worry.

With DD I had weekly US, she consistenly measured 1 wk behind when measured on the (older) machine used by the nurse. When I would have them on the much newer obs US the dates were spot on, so variation in dates can be related to the US machine used.

With my first scan for DS, I thought I was almost 7w but only measured 5w3d. I should have been due the 4th of the month but my EDD was pushed to the 15th! That certainly had me worried but apparently even though you can chart when you ovulate (which I had done), it can still take up to a week for full implantation to occur and sometimes even longer.

By 38w, I was told he was measuring really small and would only be about 2.5ish kg. I had him at 38w3d and he was 3.4kg, so scans are certainly not infallible!!

Wishing you a nice smooth pregnancy.

They changed my dates by 4/5 days.  I knew exactly when we conceived and when my LMP was-we had been trying for #2 for 7 years so i was charting AND hubby works away.  The hospital even changed the date of my LMP *rolls eyes* so its now in the paperwork as starting the day it finished!  I'm just assuming that as they say she was conceived while hubby was away it was just that the girl sperm lives longer and that it took those extra days to make it's way into the egg.  My 1st us showed a yolk sac, but no fetal pole, a week alter exactly there was a baby with a heartbeat of 167!  I have just over 6 weeks to go now

#18 lynneyours

Posted 28 February 2013 - 11:26 AM

Me too - with DD2, we only DTD once, on CD 25 or so (reallllllly late) and then they pushed her EDD back a week, which would have had me conceiving on day 1 of my period.  original.gif  I just assumed the egg and sperm hung round a bit, and she was born on her new EDD!

#19 Guest_Sunnycat_*

Posted 28 February 2013 - 11:46 AM

Both my pregancies have had really different measurements for the early scan.

With this one, according to my dates (using OPKs so rough idea of when I ovulated) I was 6w3d but the scan said 5w5d. We only had sex once during that time, so it would have been virtually impossible to get a positive test and to get pregnant if I were to go by the scan date.

Try not to stress too much. Good luck!

#20 Starrydawn

Yes I knew my exact dates and was 7wks and a day and it measured 6 weeks exactly. By the time it was the 12 week scan my dates were correct.

My scan showed my date out nilly 3weeks, I still don't understand what or how this had happeden but I'm now 31weeks along. Keep you chin up, these times are very testing for 1st tirmester

I had a scan recently when I was 6weeks 3 days. The sonographer said I was def 5weeks 3 days. 2 weeks later my Ob's scan matched my dates perfectly. When they are that small, it's so easy to measure incorrectly. I hope you get some peace of mind soon.

#23 Roobear

Posted 02 March 2013 - 03:17 PM

I measured 6 days behind for DD and 6 days for DS meaning that I got bfp's at 8 and 7 dpo respectively. I was really worried at the time and even had a follow up scan with DS but all worked out. Fingers crossed for you and best wishes! original.gif
