Now, the tail that was with the embryo disappears and looks like a little human being. Your baby’s essential body parts undergo a critical developmental transformation in the months to come (2) (3).

The developed placentaiA temporary organ that develops during pregnancy and provides the developing fetus with oxygen and nutrients now takes up the final task of producing hormones. The development of essential body parts is complete in this week of pregnancy. In the coming weeks, these body parts will be better defined structurally.

To get relief, avoid eating gas-producing foods such as cabbage and beans. Also, don’t take any OTC anti-gas medication unless directed by your doctor.
  1. Heartburn and constipation: Hormonal changes during pregnancy relaxes the esophagus and stomach. Additionally, it slows down the food movement along the digestive system, leading to issues such as heartburn (or reflux) and constipation.

This scan dates your pregnancy, estimates your due date, checks your baby’s growth, and can tell how many babies you are expecting (18). It can also show some minor yet notable details, such as limbs. Megan Wilmarth, an avid blogger, shares her ultrasound experience at nine weeks of pregnancy. She says, “The most moving part of the ultrasound was seeing our little one’s heart fluttering at what seemed like a million times a minute! The baby was perfectly still, all cozy in the fetal position with what looked like its legs tucked up under and its arms up around its head (i).”

Tips For A Better 9th Week Pregnancy

Expert Tips From A Gynecologist

1. Continue medical advice

You should continue the intake of folic acid as prescribed by your doctor. Visit your doctor more frequently. He will advise some baseline tests and sometimes special tests.

These tests include a specialized ultrasound scan called Nuchal Translucency Scan (NT Scan) to predict whether your baby is at risk of developing any abnormalities or not. You may opt for tests like first trimester serum testing (blood tests) to predict the risk more accurately.

You should not take any drugs without consulting doctors as they may be harmful for the developing baby.

2. Do not confine yourself to home

You should continue your daily activities that are possible without discomfort. Absolute bed rest may be harmful for you and your baby. So continue your normal activities indoor and outdoor but take care while travelling to avoid injury. Avoid prolonged sitting while travelling. Do not do strenuous exercise.

3. Intimacy

Most of the couples do not know whether they should continue physical relationship or not. Many fear that it might harm the pregnancy. But the fact is that sexual activity is not harmful, in general. However, it should be avoided if you have bleeding in pregnancy or other high risk factors like previous miscarriages.

Now is the time to receive prenatal care and here is how you need to go about it:

  • Join a support group: If you are not able to cope with the stress and anxiety, you should join a support group. In support groups, you get to talk with other pregnant women that help you cope with the feelings you are undergoing. Additionally, there will be professionals who specifically deal with moms-to-be to calm their emotions.
  • Beat stress: Whenever you feel overexcited or stressed, try doing deep breathing exercises or going for a brief walk. Doing so can reduce anxiety and lower your stress levels. Physical activities can release endorphins in the brain, which help increase overall happiness by reducing stress levels.
  • Communication with your partner: You should always feel free to express your feelings with your partner. It helps him understand what is going on with you.
  • Connect with your growing baby: Diane Sanford, the clinical psychologist, highly recommends setting at least 10 minutes aside every day to connect with your baby. You can start by relaxing in a calm area by taking deep breaths. Think about the dreams and hopes you have for your baby. You can also think about what kind of parenting style you can adopt for your child. It is a healthy way to get rid of stress and allows you to connect with your child in a better way.

  • Safe home: Some cleaning products, paints, mosquito repellents, and solvents contain toxic chemicals which can harm your pregnancy. Hence, mothers should minimize their exposure to these chemicals by following precautions, such as asking someone else to clean the home and keeping their home well-ventilated (19).
  • Comfortable sleep: During this week, you may feel more tired because of the hormonal changes, morning sickness, and trouble sleeping. You may not get proper sleep because of the frequent visits to the bathroom. Try changing your sleeping positions if you are facing difficulty sleeping (20).
