2 Weeks Pregnant

    2 Weeks Pregnant

    At 2 weeks pregnant, this is just the start of a wonderful journey. Did you know you can nourish your baby’s developing brain even before you’re pregnant? Explore our week-by-week guide to find out what’s in store for your baby and your body in your 2nd week of pregnancy.

    At 2 weeks pregnant:

    • Your baby is a little too small to compare to anything just yet
    • You’re officially at the beginning of the journey
    • The countdown starts right about…now!

    What happens during the second week of pregnancy?

    • You've reached the end of your menstrual cycle. The gestational-week counting starts the first day of a woman’s last menstrual period (LMP), but there is no baby conceived in the first two weeks. Because it’s really difficult to pinpoint the exact date of conception, most doctors count back to the known LMP date (before conception) when dating the 40 weeks of pregnancy, also called your baby’s gestational age.
    • Your egg is released by your ovary. During week 2, your egg travels down the fallopian tubes in hopes of being fertilized by the sperm.
    • The lining of your uterus is thickening. This readies it to receive the fertilized egg.
    • You may conceive this week. It’s during week 2 or 3 that egg and sperm are most likely to unite.

    What should I be feeling at 2 weeks pregnant?

    It’s early days and hey, you may not even be pregnant. If you are, there are going to be subtle signs that will become obvious in the next few weeks. These can start with a more acute sense of smell, aching or tender breasts, light spotting and cervical mucus.

    Being 2 weeks pregnant is an important time for you and your baby. Here is some advice on how to adjust to this new stage.

    • If you’re planning to have a baby, start well ahead on the supplements as you start trying as the baby's neural tube — what later becomes the baby's brain and spinal cord — starts developing that very first month of pregnancy
