As your baby develops, your body undergoes changes in your biological and metabolic processes. You may not feel pregnant yet, that’s because the early signs of pregnancy can occur anywhere from week two to week six in the trimester. Read about the different early pregnancy symptoms and inform yourself about what to expect during your first trimester.
This is a complete guide to everything you need to know regarding your baby’s development in the first trimester and situations that you need to be prepared to handle.
The Length of the First Trimester & What to Expect
The first trimester is the period of 12 weeks from the date of conception. If you are unsure of your conception date, then visit your doctor to get an accurate idea of the date. Knowing your conception date is important as it sets the due date of your baby.
Your Baby’s Growth during the first Trimester
In the first trimester of your baby’s life, the fertilized egg develops into a blastocyst and begins to cell-divide. After two weeks, the blastocyst will move to the uterus where it will implant itself in the wall of the uterus. This implantation process sometimes results in spot bleeding which can confuse you into thinking you have had your period.
After this initial phase, things begin to pick up speed and your baby starts to develop into a fetus. Here is a brief timeline of what you can expect in the first trimester of your pregnancy.
Your baby’s bones, limbs at the 6 week mark. Extremities such as toes and fingers begin to form at around the 10 week mark
Nails and hair begin to take shape between week 5 and 8 and your baby’s digestive system develops at week 8, forming intestines and interestingly enough, your baby should have been through two sets of kidneys already.
Senses of touch around the face develop at week 8 and receptors on the soles of the feet and palms of the hands develop by week 12.
Optic nerves begin to grow at week 4 and the retina develops at the eight week mark. By week 5 your baby’s heart will have shown its first early stages of development and begins to beat.
The baby’s brain becomes active at around the eight week mark and will begin to move the baby’s body in your womb.
