Normal Growth Rates for Your Baby During Early Pregnancy

Q: Normal Growth Rates for Your Baby During Early Pregnancy

Hello： On October 19, a pregnancy test confirmed pregnancy and an ultrasound showed a gestational sac measuring approximately 0.4 cm (about 4-5 weeks gestation); on November 3, it measured about 6-7 weeks gestation, while a normal gestational sac is typically over 2 cm. <br>Since

How can we determine if a baby's growth rate is normal?

Hello, we have been trying to conceive since August without contraception.
My menstrual cycles are longer, with periods on 5/16-19, 7/1-5, and 8/16-21.
I was expected to get my period on 10/1, but it did not arrive.
On 10/11, I took a pregnancy test that showed negative results, and the doctor advised me to test again in two weeks.
On 10/17, I tested positive for pregnancy.
I went for an ultrasound on 10/19, and it showed an embryo.
On 10/21, I experienced slight bleeding and consulted the doctor, who mentioned that the baby was about 0.4 cm, which seemed small.
During my follow-up on 10/27, the measurement was about 0.7 cm, which was smaller than the expected 1 cm.
The doctor suggested that if the measurement does not reach 1.5 cm by the follow-up on 11/3, it may indicate that I need to consider termination.
I would like to ask if the baby still shows signs of growth, even if it does not meet the doctor's standards, should I follow the doctor's recommendation to terminate? I feel very confused.
If the conception date was later, is it possible for the baby to be smaller?

Hello: On October 19, a pregnancy test confirmed pregnancy and an ultrasound showed a gestational sac measuring approximately 0.4 cm (about 4-5 weeks gestation); on November 3, it measured about 6-7 weeks gestation, while a normal gestational sac is typically over 2 cm.
Since it has not reached 1.5 cm, there is a high possibility of a blighted ovum.
However, if you are concerned, you can follow up until 8 weeks, around November 10, at Hsinchu Hospital, Department of Obstetrics and Gynecology, with Dr.
Cheng Jin-He.

Understanding the growth rates of a developing fetus during early pregnancy is crucial for expectant parents. In your case, it seems that you have been monitoring your pregnancy closely, and I understand your concerns regarding the size of the embryo and the recommendations from your healthcare provider.

First, it's important to recognize that fetal growth can vary significantly from one pregnancy to another. The measurements taken during ultrasounds are estimates and can be influenced by several factors, including the timing of the ultrasound in relation to ovulation and implantation. In your situation, if you conceived later than expected, it is entirely possible that the embryo is smaller than the average size for that gestational age.
The size of the embryo is typically measured in terms of crown-rump length (CRL), and there are established growth charts that provide average measurements for different weeks of gestation. For example, at around 6 weeks of gestation, a typical embryo may measure about 0.6 cm to 1.2 cm. If your embryo measures 0.4 cm at around 6 weeks, it may be on the smaller side, but it is not necessarily indicative of a problem, especially if there are signs of growth in subsequent ultrasounds.

The key point here is that growth should be monitored over time. If the embryo is showing signs of growth, even if it is not meeting the exact measurements expected by your healthcare provider, it may still be developing normally. It is essential to have follow-up ultrasounds to assess whether the embryo continues to grow. If the growth is consistent, even if it is slightly behind the average, it may not warrant immediate concern.

However, if there is a lack of growth or if the embryo appears to be shrinking, that could indicate a potential issue, such as a miscarriage or an abnormality. In such cases, your healthcare provider may recommend further evaluation or management options.
Regarding your specific question about whether to follow the doctor's recommendation to "handle" the situation if the embryo does not reach the expected size, it is crucial to have an open and honest discussion with your healthcare provider. They can provide you with the rationale behind their recommendations and help you understand the risks and benefits of continuing the pregnancy versus considering other options.

In summary, while it is understandable to feel confused and concerned about the size of your embryo, it is essential to focus on the growth trends over time rather than a single measurement. If the embryo continues to grow, even if it is slightly smaller than expected, there may still be hope for a healthy pregnancy. Always feel empowered to ask your healthcare provider questions and seek a second opinion if you feel uncertain about the recommendations being made. Your health and the health of your baby are of utmost importance, and you deserve to feel confident in the care you are receiving.
