10 Week Ultrasound Shows 5 Week Development

I think I am 10 weeks pregnant based on last period. During ultrasound tech said the sack was empty, definitely not a 10 week fetus. Dr. and radiologist agree the ultrasound shows 5 week development. Has anyone experienced something similar? If its a blighted ovum would development just stop, i.e. showing 5 weeks instead of 10? Also, I am not cramping/spotting/bleeding and have some of the same symptoms from my first pregnancy from which I have a beautiful 2 year old. I did have a miscarriage 6 months ago at 7 weeks and am now taking progesterone. I am 35, so that may also be a factor.

*Update 3/23: I just wanted to mention that my OB GYN ordered another HCG and Ultrasound in 2 weeks (one week from now). If I am indeed 6 weeks pregnant and not 11 I understand I should be able to see something by 7 weeks. Thanks to everyone for all your sensitive and helpful information and support. I am trying to be prepared for good or bad news. I'll let you know what happens next week.

What can I do next?

So What Happened?™

I had the ultrasound today and saw that the development had not proceeded after the 5 week mark as seen in the original ultrasound. Not too much of a surprise as I started to spot yesterday. Thank you all for sharing your personal experiences and advice, it really helped me to be prepared for this miscarriage. If anyone has advice at this point for what helped them regarding what to look for in testing, or any other advice. Please let me know. I don't seem to have too much trouble in getting pregnant but in maintaining, and it is apparently not the progesterone levels.

I had a blighted ovum(I was 21, so they're not age discriminate), and my body carried it to twelve weeks, I thought I was just past the first trimester and out of the hight miscarriage risk and then I started bleeding. If you do have one, I'm sorry. It was a strange feeling because I wanted to be sad because I had been expecting a baby, but if there never had been a baby, why should I be sad? Good luck.

L.,

I can only tell you went I went through. I had two blighted ovums and both times u/s (8&9 weeks) showed that the development stopped at 5 weeks. I had some pregnancy symptoms because my Hcg levels were up, the levels showed positive pregnancies, there just wasn't ever a baby.The next thing my doctor did was test my HcG levels again, and at that time they were going down instead of up, so I was miscarrying, and I did that naturally. Now, I was originally in for a u/s because I was spotting, so my situation was a little different. That being said, it's possible that you could have ovulated later than you thought, and gotten pg later, which would have caused the development to be behind what you had originally thought. I know that this is a stressful time for you, so hang in there! Best of luck!

Dear L.,

i too had a blighted ovum--i went in for my 8 week u/s & the gentational sac was at 6 weeks & empty. The doctor told me the sac was empty & that he should be able to see a fetal pole at this time but the sac size was at 6 weeks too--so that is when the baby stopped developing. I certainly was not waiting for that news that day..but i am currently trying again. I have a 2 1/2 year old girl & would love to give her a brother or sister.........but if i cant i am so blessed to have her!!!!

I went through the same exact thing. Yes, the development does just stop. I was also on progesterone. The progesterone is probably the reason you are not experiencing any bleeding/cramping. As soon as they confirm that it actually is a blighted ovum they should take you off of the progesterone and you will then start bleeding shortly after. GOOD LUCK Please let me know how everything goes with you. I will say a prayer for you. FYI After my miscarriage I got pregnant again at age 41, and had a perfect little baby boy, who just had his fourth birthday.

Ultrasound is accurate to the day. If you base the due date on your cycle, you could be off as much as a month. Don't worry -- each pregnancy is different.

Hi there- I have experienced that before as well. Then my daughter ended up being born at 37 weeks and she was a full pound bigger then my other children- so I think I was right all along. As long as the baby is growing and healthy- don't worry. Every baby grows at it's own pace. My last pregnancy (he's 6 weeks) they said he was measuring at 28 weeks when I was 32 weeks, but when he was born he was normal and healthy. Sometimes they're just not that acurate.

Is there a possibility your dates are wrong? I am sure your Dr. and the radiologist will recommend a follow up. If nothing changes, then they will consider it to be a problem. You will have to wait until your next ultrasound to see if anything changes unless something else happens.(bleeding,etc.) They will also probably coordinate with blood work to see how far along you should be. I am and ultrasound tech for 12 years.

L., hang in there. Your doctor should have scheduled a second ultrasound and/or blood draw. Wait and see what that says. I've had a lot of miscarriages, and they all seemed to stop growing around the 5 week mark. If this one does miscarry, I highly recommend seeing a specialist since it would be two in a row (your reg OB may not suggest it for another time or two and who wants to go through all that). I wish I'd gone to one much sooner as now I'm afraid to try again even with a plan. (((HUGS)))
