First month of pregnancy baby development and quick checklist

When does the first month of pregnancy start?

The first month of pregnancy starts from the moment when an egg and a sperm meet in the fallopian tube. During the first week after the conception, the cells in the ovum start to divide and at the same time the egg moves to the uterine cavity. On the eight day after the conception ( the beginning of week 2) it gets to the uterus and implants onto its wall. Then it begins to grow.

When you visit your healthcare provider, he will count the first day of your last menstrual period as day 1 of your pregnancy. So, month 1 of pregnancy starts from your last period until the end of week 4.

    Talk to your doctor about your pregnancy symptoms, and discuss with him all your concerns.
  • Ask your doctor about which prenatal vitamins you should take.
  • As you found out that you are pregnant, you should stop drinking alcohol and quit smoking to save the life of your foetus.
  • You should know some hazards around the home to avoid them during pregnancy.

Your baby development in the first month of pregnancy:

In this stage, your baby is now looking nothing like a baby or even a foetus.
The baby now is just a group of cells multiplying and growing rapidly. The outer layer of cells will become the placenta and the inner layer will grow into an embryo.

Once your growing embryo travels from your fallopian tube into the womb, it will burrow itself into the lining of the uterus. This is called implantation.
During the first two weeks of your embryo’s development, a very primitive face starts to form. Your baby’s eyes, mouth, lower jaw and throat have started to develop.

ts blood cells are also taking shape to prepare for circulation.
At this point, your baby will measure approximately five millimetres, so he is tinier than a grain of rice.

One month pregnant belly:

During the first trimester, your waistline will begin to expand as your baby and uterus grow larger. Depending on your size before pregnancy, you may not notice this change until the second trimester. It is normal to gain no or little weight in your first trimester.
