Why Miscarriages can be Misdiagnosed

I am not a medical professional. The information I share is meant to supplement the information given you by your doctor. If you feel your doctor is not doing enough for you or not willing to listen to your concerns, I strongly encourage you to take what you've learned here and get a second opinion.

More than four years ago, I shared the story of my two misdiagnosed miscarriages on Epinions.com. You can read my original article Can a Miscarriage be Misdiagnosed to find out more about my own misdiagnoses.

I could not have imagined then, how sharing my story would change my life as well as the lives of many other women. As a result The Misdiagnosed Miscarriage was born.

Over the coming days, I'll add more about my journey here. Really, I only have one thing I hope everybody takes away here. Do not feel pressured into ending your pregnancy too soon. If you are not 100% certain this is a miscarriage and your doctor is pushing you to end the pregnancy quickly, you can wait out the diagnosis. Studies show that having a natural miscarriage can be just as safe, if not safer than having a D&C as long as you know the signs of infection. If you have signs of infection, see your doctor immediately otherwise stay monitored and take the time you need to be certain. No woman should be rushed through treatment if she is not 100% sure she is losing the baby. Don't get me wrong, though. Often times, women wait and end up miscarrying but sometimes they wait and are rewarded with a viable and successful pregnancy. That is what makes getting the word out so important.

By sharing my story, I don't want to give false hope. I do, however, believe in hope. Reading this site or posting on the misdiagnosed site will not decrease your chance of miscarrying. However, it may prevent your doctor from ending what may turn out to be a viable pregnancy. As I look at my now four-year-old daughter, I am thankful I turned down that D&C twice. Even if my pregnancy had turned out to be non-viable, I could not have lived with the 'what ifs'. I needed to know with certainty and every woman deserves that same certainty.

Over the last few years of talking to women, we've seen some patterns emerge on the Misdiagnosed Miscarriage site.

I'd like to share a bit of what we've learned.

Question #1:
My doctor says my hCG levels should rise every 48 hours. Is this true?
Answer:
No! In early pregnancy, levels should double more quickly but as the first trimester progresses, those levels will slow, plateau and even begin to decline.

Follow up to Question #1:
Well then, how quickly should my hCG levels rise?
Answer:
According to conceivingconcepts.com levels typically look like this:

less than 1200 -- doubling time 48 to 72 hours
1200 to 6000 -- doubling time 72 to 96 hours
more than 6000 -- doubling time can be more than 96 hours.

Question #2:
My doctor has said that I am far enough along, the baby is always seen by this point on the ultrasound. Is that true?
Answer:
I can tell you what the ultrasound literature states and what your doctor has learned:
"A pregnancy is anembryonic if a transvaginal ultrasound reveals a sac with a mean gestational sac diameter (MGD) greater than 13 mm and no yolk sac, or a MGD >18 mm with no embryo." To give you an idea, a 13 mm gestational sac is usually thought to be seen around six weeks and an 18mm sac, around seven weeks or so.
Now, ask me if that is true? I will tell you emphatically, "No!" At about 22mm, my gestational sac still looked empty and it was 28.5 mm before my baby was seen. Numerous women have shared similar stories on the misdiagnosed site.

Question #3:
My doctor said that my hCG levels are high enough that a baby is always seen. Is this true?
Answer:
No. Again, found on many medical sites, "a yolk sac larger than 7 mm without evidence of a developing fetal pole suggests a nonviable pregnancy" and "The embryonic pole usually becomes evident at a level of approximately 5000 mIU/mL, and the fetal heartbeat can be seen in the vast majority of normal gestations when the hCG level reaches 10,000 mIU/mL"
Let me tell you, this panics many women. However, my own levels were well over 100,000 before anything could be seen and, again, many women report the same on the misdiagnosed site.

Question #4:
My doctor says I have a retroverted (AKA tilted or tipped) uterus but says that has really no bearing on the pregnancy, is this true?
Answer:
This is partially true. A retroverted uterus does not cause a miscarriage. It simply means your uterus is tilting back rather than forward. This usually straightens itself out by the end of the first trimester.
However, that said, a disproportionate number of women are mistakenly misdiagnosed when they have a tilted uterus. Many of these babies stay 'hidden' longer until up to nine or even ten weeks. Also, we've found that many women who know exactly when they conceived look one to two weeks behind during the transvaginal ultrasound even when this is not possible. Then, during their second trimester ultrasound when their uterus is in a more 'normal' position and they have the abdominal ultrasound, their dates are often right on again.

Question #5:
I am eight weeks and we saw the baby on the ultrasound with no heartbeat. Is there no hope?
Answer:
I have been told that if you ever see the baby on a first trimester ultrasound with no heartbeat, you should wait at least seven days and have a follow-up ultrasound. Sometimes the angle is wrong or sometimes the baby is just too small still. Ask for that follow-up ultrasound and give it at least a week. If the baby is still too small, you want enough time for everything to be seen if the pregnancy is indeed viable.

Question #6:
I've been told that doctors would never misdiagnose something as important as miscarriage, is this true?
Answer:
No, and that is the point of this page. We've been collecting stories from women who were misdiagnosed. Some women were given no hope whatsoever and other women were simply told by their doctors not to get their hopes up. We are continually adding to this post: Misdiagnosed Stories. If you have a story you would like to share, please add it to that forum.

After eight years of trying to get misdiagnosed miscarriages in the news, we're finally seeing results. Here is an article by Time Magazine.

Ultrasound Guidelines May Wrongly Diagnose Miscarriage

A snippet from that article:

As if the worry over potential miscarriage weren't stressful enough for newly pregnant women, research released Friday shows that current guidelines for using ultrasound to determine that a pregnancy has ended may not always be accurate.

The four new studies looked at U.K. ultrasound specifications, but when the findings are extrapolated to U.S. guidelines, the researchers suggest 1 in 23 women diagnosed with miscarriage could still have a viable pregnancy.

On the Misdiagnosed Miscarriage site, we believe that that figure might be much higher. For women diagnosed with a blighted ovum, something like one in five may be much more accurate.

I hear from women all the time who are going through their own miscarriage scares. Going through a miscarriage can be an incredibly lonely time. I know from my own experience, not many people understood or were able to empathize. You'll find a wonderful group at the Misdiagnosed Miscarriage group or you can just email me at bonzobean@gmail.com
