Congratulations on your pregnancy!

Be it through IVF or IUI, 9-month pregnancy is an exciting time, filled with joy, fear, anticipation, and curiosity. First month pregnancy is not similar to all. Parents are usually getting assurance and reassurance based on first month pregnancy symptoms. That’s why we have created blogs on what to expect during each stage of your pregnancy, including the first month. This blog is your guide on the first month of pregnancy, fetus development, and proper prenatal care during this time. So, let’s get started!

First Month Pregnancy – Prenatal Cycle Starts 1-4 Week

The first month of pregnancy is calculated when you observe the missed period. Your body starts showing symptoms like nausea, heavy breast, fatigue, and sometimes spotting. Pregnancy is confirmed only after your urine and blood test report shows a high level of hCG hormones. The test result is positive, then.

To calculate the pregnancy week, we count from the first day of your last menstrual period, and it is during this time the egg is fertilized by sperm and implanted in the uterus.

We wish a healthy body and mind to both you and your baby. But, if you experience any of the following symptoms, consider them as danger signs and rush immediately to Aastha Fertility Center.

Overview of Fetal Development

Your 16-17 days baby is still an embryo and will resemble a small bubble. Your child is still tiny, and the resemblance of a baby is still too young to see. But you can certainly listen to their heartbeat. 

But within this first month, the neural tube start forming, which will eventually be the baby’s brain and spinal cord. Also, Placenta, the most important cord that would provide oxygen and nutrient to your baby, begins to develop.

  • Avoid doing a high-intense workout like Tabata or HIIT to avoid any risk of falls or trauma.
  • If you are cleared for exercise, it is generally recommended to engage in prenatal yoga.

Sleeping Postures During The First Week of Pregnancy

There is typically no need to focus too much on your sleeping posture in the first 30 days of the pregnancy, as the fetus is too small to be affected. Still, you can follow these tips for more relaxation and comfort for you and your baby. 

  • Sleep on your left side during pregnancy as it improves blood flow to the uterus and fetus.
  • To provide additional support, place a pillow between your knees, under your belly, or behind.
  • If you have the habit to sleep on your belly, it is best to start avoiding it to prevent discomfort later in pregnancy.
  • If you are experiencing heartburn or acid reflux during pregnancy, try keeping a pillow under your head to help alleviate symptoms while sleeping.
  • Sleeping on your back after the first trimester can reduce blood flow to the uterus and potentially harm the fetus, so start practising sleeping on your sides.
