This topic is HARD. If you experience or have experienced a non-viable pregnancy, it can feel like no one understands. Your medical staff, the people you pass on the street, those somber-eyed ladies in black and white photos—we are all touched by this unique form of tragedy in one way or another at some point in our lives, even if we never know it.
That said, be sure to ask about the pregnancy viability milestones your provider uses, as their information and how they relate that to you is going to more important than any other resource. If, on the other hand, you are currently experiencing or are in danger of having a non-viable or at-risk pregnancy, my heart goes out to you—as does my hand.
As you can imagine, a lot goes into losing viability as a zygote. That little seed pod needs very different conditions than a fully formed and growing embryo; even further still are the requirements for a legit fetus or an actual baby.
There are a lot of similarities and correlations between a non-viable pregnancy and a miscarriage, mama. They overlap a lot, actually. Things like genetic issues may leave the zygote or fetus alive but with a low or null chance to survive beyond the womb.
Yes, you CAN absolutely have a non-viable pregnancy but no miscarriage. The products of conception may have to be removed surgically if the pregnancy is non-viable.
As you can imagine, mama, a lot goes into determining whether or not a zygote, embryo, or fetus presents a viable pregnancy. Because of the drastic nature of a non-viable pregnancy, it is very important for your health care provider to be as certain as possible before declaring the pregnancy non-viable.
You can read more details about when to call your doctor during pregnancy which might help! As with testing for the pregnancy itself, measurements of hCG human chorionic gonadotropin along with an early ultrasound can help in diagnosing the potential for complications. Diagnostic criteria for a non-viable pregnancy in the first trimester are imperfect enough that your doc should always be erring on the side of caution. Ultimately, there is no silver bullet amount of hCG that can tell us whether or not a pregnancy is non-viable.
In the case of ectopic pregnancy , also called a tubal pregnancy, the baby implants in the fallopian tube instead of the uterus. This is a life-threatening condition that requires immediate medical attention once discovered. It is usually discovered by the 8th week after your last menstrual period. A molar pregnancy occurs when a fertilized egg develops into an abnormal growth instead of a baby.
There are two types of molar pregnancy:. Trophoblastic disease can turn into cancer if it is not successfully treated. Any of the following symptoms could be signs of molar pregnancy:. About half of all first trimester miscarriages are caused by a blighted ovum. Also called anembryonic pregnancy , this condition happens when a fertilized egg fails to develop into a baby.
By about 5 to 6 weeks after your last menstrual period, your baby should be clearly visible on an ultrasound. With a blighted ovum, the placenta and pregnancy sac will appear, but no baby will be present. This heartbreaking condition is usually caused by chromosomal abnormalities or improper cell division immediately after fertilization.
Symptoms of a blighted ovum include the typical symptoms of early pregnancy, along with abdominal cramping, vaginal bleeding, and a heavier than normal period when your body expels the placenta and pregnancy sac. Korevaar TIM, et al. European Journal of Epidemiology, Cervinski MA, et al.
