Subchorionic Hematoma Resolving: Important Signs You Should Know!

Bleeding during pregnancy: ever experienced it? Well, spotting or bleeding are the two scariest words for pregnant women you must agree with me! But did you know, that not every bleeding leads to miscarriage? In fact, there are conditions during pregnancy when females experience bleeding on and off and subchorionic hematoma is one of such conditions.  

So, what is a subchorionic hematoma and what are the signs subchorionic hematoma resolving

Well, approximately 3% of women during their pregnancy suffer from the subchorionic hematoma that goes away over time. However, in rare cases, it can also lead to miscarriage and increased complications during pregnancy. When it resolves, women typically observe a reduction in the bleeding or it might just end up as spotting. 

In this write-up, you’ll learn all about the SCH, its causes, symptoms, treatment, and signs of its healing. So, to learn an in-depth detail about hematoma, let’s delve into it! 

The cause is still unknown but a subchorionic hematoma usually happens due to the dislocation of the placenta during the first twenty weeks.

Subchorionic Hematoma

When you’re pregnant, your fetus is well-protected and enclosed within multiple membranes. The layer that surrounds the embryo is called the amnion and the layer that connects the embryo with the wall of the uterus is called the chorion. 

Any bleeding beneath the chorionic layers is called a subchorionic hematoma. 

Thus the bleeding continues and accumulates between the chorionic layer and uterine wall leading to a hemorrhage and eventually hematoma. Its symptoms are:

A subchorionic hematoma is usually seen in the first 20 weeks of gestation typically and when it is observed within two weeks of gestation, it is referred to as implantation bleed.


You might suffer from a subchorionic hematoma in the second trimester or during any period of gestation but it rarely causes miscarriage. 

Subchorionic Hematoma Size Chart

When seen on a radiograph, you’ll observe an elevated crescent-shaped chorion usually extending towards the margin of the placenta. The size of a hematoma depends on how long it has been bleeding. The size chart is:

SizeComparison With The Sac
Small Less than 20% of the size of the sac
Medium20-50% of the size of the sac
LargeMore than 50% of the size of the sac


The cause is still unknown but a subchorionic hematoma usually happens due to the dislocation of the placenta during the first twenty weeks. The placenta fixes the embryo to the uterine wall and it might get detached causing bleeding and leading to subchorionic hematoma. 

Some other causes are: 

  • Uterine deformity 
  • Trauma 
  • In-vitro fertilization 
  • High blood pressure
  • History of pregnancy losses

how long does subchorionic bleeding last? Well, bleeding due to subchorionic hematoma is puzzling because you can experience, light spotting to heavy clotted bleeding and even no bleeding at all! Typically, the bleeding stops naturally; however, it might get dragged up to the mid-trimester. 

How Often Does Subchorionic Hematoma Result in Miscarriage?

Bleeding and spotting are quite common during pregnancy but if it is a subchorionic hematoma, then you must get yourself checked. It’s not that every subchorionic hematoma would end up as a miscarriage but it can happen rarely. 


The subchorionic hematoma miscarriage rate was once studied in a research in which 13/44 women with subchorionic hematoma faced miscarriage whereas 25 out of 198 women with normal pregnancy experienced miscarriage. So, 30% of women experienced pregnancy loss with it. Hence, subchorionic hematoma increases the chances of miscarriage during pregnancy. 

Signs Subchorionic Hematoma Resolving in Pregnancy

Usually women get confused between subchorionic hematoma and spotting because during pregnancy most women bleed in the first two trimesters. However, spotting doesn’t involve heavy bleeding whereas subchorionic hematoma does. In fact, to cope with bleeding, sometimes you might even have to use panty liners. 

One of the most significant signs of subchorionic hematoma resolving is the reduction in bleeding. It gets limited to a little dark red/brown discharge that eventually goes away as soon as the healing process is completed. 

However, if you start bleeding less, then it does not mean to forget the precautions. You need to be even more careful now because you’re on the verge of healing. Avoid intense exercises, lifting heavy objects, and all kinds of chores. Avoiding sex and complete bed rest are recommended.

How Do You Know If Your Subchorionic Hematoma Has Healed?

When you get a subchorionic hematoma, there’s no way you can treat it. There aren’t any medicines to cure it, so, all you can do is, take precautions, and avoid stress. Reduced bleeding is the most prominent sign of subchorionic hematoma resolving. Hence, bleeding goes away on its own and it is usually when the healing completes. 


How to Shrink a Subchorionic Hematoma?

When your ultrasound shows you’re suffering from a subchorionic hematoma, your doctor will first judge the size of your hematoma, and considering the size, he’ll suggest you a treatment. Doctors often recommend 

If the size of the hematoma is large which is more than 50% of the sac, then you should avoid physical stress, exercise, and sex. Rh-negative women are also given RhoGam injections to reduce the chances of risk in future pregnancies. 

Many women ask about the best way to lay with a subchorionic hemorrhage and doctors suggest them to sleep on their side to facilitate the blood circulation within the fetus. 

Foods to Heal Subchorionic Hemorrhage

It’s not that a particular diet will heal your hematoma but it can surely aid in the process of quick healing. Aside from diet, the foremost things to do are avoid lifting heavy objects and just rest! Yes, the more you rest, the quicker it heals. 


Avoiding all types of physical activities is very important for resolving it. When it comes to diet, firstly, drink plenty of water, and secondly, consume foods that are rich in fiber to reduce the chances of constipation. Foods such as leafy vegetables, red meat, eggs, beans, and all those rich in iron are recommended.  

What Irritates a Subchorionic Hematoma?

When you’re having a subchorionic hematoma, you must limit your physical activities. Strenuous workouts, lifting heavy objects, walking, jogging, running, sexual intercourse, and all type of activities must be avoided to prevent the risk of miscarriage. Hence, for a smooth pregnancy, you should try avoiding all the aforementioned triggers while having a subchorionic hematoma. 

Can subchorionic hematoma happen again? Well, some women experience recurrent subchorionic hematoma and the cause is almost unknown. However, this isn’t for everyone as avoiding stress and intense activities can help prevent it. Moreover, the treatment criteria remain the same and require taking full precautions. 

So, do most subchorionic hematomas resolve? Well, most of such hematomas resolve on their own. However, some pregnancies become worse and end up as miscarriages


How long does it take for a subchorionic bleed to resolve?

There isn’t a concrete number of days for the subchorionic hematoma to get resolved. Typically, bleeding lasts for a few weeks and goes away on its own. Healing time also depends upon the complications and size of the hematoma. Hence, healing might occur till the second trimester. 

How does a subchorionic hematoma heal?

A subchorionic hematoma is caused due to the accumulation of blood between the chorionic layer and uterine wall. So, it usually heals naturally on its own by dissolving naturally. However, the treatment depends upon the size of the hematoma, and healing might involve progesterone and dydrogesterone.  

Is it normal to bleed on and off with a subchorionic hematoma?

Yes! Women often confuse SCH bleeding with normal spotting whose distinguishing feature is that women with subchorionic hematoma experience both spotting and heavy vaginal bleeding whereas normally there’s spotting only. A reduction in bleeding is a major sign indicating the healing process. 

Do most subchorionic hematomas resolve?

Yes! Most of the subchorionic hematomas resolve on their own without causing complications. However, in a few cases, it might risk the pregnancy and lead to miscarriage. Resolving SCH requires strict bed rest and doctors recommend avoiding strenuous activities, intense workouts, jogging, walking, and running. Hence, limiting your physical activity can help in the SCH’s healing process. 

Final Verdict

There aren’t multiple signs of subchorionic hematoma resolving; however, a major indication of it is the reduction in bleeding. In some cases, it is just limited to spotting which is when women realize that it is healing. 

SCH is of no risk if handled properly; however, if treated with carelessness, then the consequences might become intolerable. Avoiding physical stress, sex, and complete bed rest is recommended while suffering from SCH. 

Such types of hematomas heal on their own but healing time depends upon the size of the hematoma. Doctors sometimes recommend progesterone and dydrogesterone to boost the healing process. But nothing works if you don’t take the precautions normally. So, follow up on your doctor’s advice, and hopefully, you’ll have a smooth pregnancy!
